(2) Flag Flag area is 8 bytes from the “flag top address” set in the master station JW-20CM parameter, monitor communication condition.
(3) Error code When an error occurs in the JW-20CM, it stores the occurred error’s code to system memory #170 of each station’s PC.
Remarks • The error code stored in the system memory #170 is shifted to #170 to #177 one after the other as new errors occur. Thus, the system memory can store up to 8 errors. When the PC is operating by RAM, these error codes do not disappear even after turning OFF the power. The contents of system memory #170 to #177 are kept storing after the JW-20CM recovers from the error.
(4) Recovery method at communication errors ① Check flow chart Occurrence of error Connection status of cable/connector are normal. NO See “Check cable/connector” on next page. YES See “During initial communication” on page 8·57. YES First communication? NO NO Does the error occur continuously? 8 See “When the communication error occurs instantaneously ” on page 8·59. YES See “When the communication error occurs continuously” on page 8·60.
② Check cable/connector As errors on the junction from the main cable to the drop cable or the contact failure on the connecting point of each station or errors of the master module are assumed, check with the following procedure. Set the error operation mode of a JW-20CM master module to “2.” FT lamp turns ON YES Exchange JW-20CM NO Monitor “individual communication flag” in support tool.
• If the bus cable between the slave station 05(8) and 06(8) is disconnected in the following system. 03(8) 02(8) 01(8) 04(8) Master station 05(8) B C D Disconnection A 06(8) 07(8) State of an individual communication flag D7 6 5 4 3 2 1 D0 OFF Unstable OFF Remove the connector on point A, and turn ON the termination resistance of the master station. As the communication possible stations 03(8), 02(8), 01(8), and 04(8) are normal, the state of communication monitoring flag is as follows.
③ During initial communication (start-up of the system) Check the error code of master station · When the master station indicates error code BF(H) The cause may be a parameter setting error of the master station. Check the master station parameters. (See the next page) · When the master station indicates error code C1 to FF(H) The cause may be a error of slave station. Check the error code of slave station.
Parameter setting range · When fixed allocation is used, set parameter within the range shown below: ｺ0000 Number of slave stations (1 ≦ n ≦ 32 or 63) Remote I/O top address Number of slave station I/O points (fixed to 64 points or 128 points) B1 to Bn : Blank between stations 1 to n : A: N: A 1 N B1 2 N B2 • • • N ｺ1577 (Setting of JW model special I/O module) 0 to 128 bytes in total per remote slave station 0 to 512 bytes in total of all stations Data register Number of module
④ When the communication error occurs instantaneously. Cause may be: • Noise on the communication line. • Fault of a communication module. • Fault of a communication cable. Check the error’s timing. When the error occurs synchronous with a peripheral industrial robot’s operation, noise to the communication line may be a cause. Consider arrangement of the wiring route. Identify the error station. When the error occurs at only the specific station, the cause may be the station or nearby.
⑤ When the communication error occurs continuously. Identify the error station. Specify the error’s station using the communication flag etc., (see page 8·51) and error code (see page 8·47). Then check this station. • Check the power of the error’s station. • Check the error code of the error’s station.
Chapter 9 Data Link 9-1 Description for data link function · The data link function us used to send and receive ON/OFF signals (relay link: max. 2048 points) and numerical data (register link : max. 2048 bytes) by PCs or between PC and personal computers connected in the satellite net system. · The master station and slave stations are connected using a single coaxial cable. As the JW-20CM network module can control the data communications, the PC does not need any special programming.
9-2 Communication method [1] Data link (standard function) Each station sends data in its sending area cyclically and stores data received from other stations in its receiving area. Station number 00(8) Station number 01(8) Station number 02(8) Station number 03(8) ： Sending area ： Receiving area For the JW-20CM to execute automatically these sending and receiving procedures, a special program for communication is required. Data link have relay link and register link. They can use at the same time.
(2) Register link function Mainly used for sending and receiving numerical data. [Example] In the case of sending 1 byte data from a master station and slave station 01 and 02.
V5 [2] Data link (Memory capacity save function) The memory capacity save function is to provide a part of the data link area in the slave station data memory as a receiving area. A slave station can receive only the required area by relay link/ register link so that the slave stations can save on use of the memory area. As this function can unify the receiving area address and the sending area address of each slave station, the same program can be used for each slave station.
[3] Link function with specific station (F200/F201 link function) There is a function for communicating data other than the parameter setting values using the PC's application instructions F-200 (write to ports) and F-201 (read from ports). The JW-20CM communicates data while executing data link operations. See page 13·22 to 13·25 for application instructions F-200 and F-201 in details. See instruction manual of ZW-98CM and ZW-20AX in case that communicating with host computer.
[4] SEND/RECEIVE function Different from the data link, the SEND/RECEIVE functions are functions which exchange the data of the required station of the required time between a PC and a personal computer or between PCs. The SEND function is the function which writes in the data after assigning the station to send data to, and the RECEIVE function is the function which reads out the data.
(1) Instruction system The PC's application instruction F-202/203 (open channel), F-204 (sending instruction), and F-204 (receive instruction) to send and receive data between modules in a network, and from a module in a network to an upper stream computer is used. • In this instruction, the function is completed after the target station replies. A special program is not needed in the connected PC station.
[Example ] In case of writing data of 8 bytes to slave station 03(8) Module number installing own station JW-20CM : 2 Channel number using own station JW-20CM : 0 Data area of slave station 03(8) : 0 (file number) Receive top address of slave station 03(8) : Register 09000 (file address 004000(8)) Send data top address of own station :ｺ1000 ｺ1000 ｺ1001 ｺ1002 ｺ1003 ｺ1004 ｺ1005 ｺ1006 ｺ1007 Receiving data Target station register 001 002 003 004 005 006 007 010 Port No.
V5 (2) Data memory starting system The data memory starting system is the system which starts the SEND/RECEIVE functions without using exclusive instructions. Set the target station number, data memory address, etc. on the specified data memory (communication information storage area). You can increase the amount of data to be transferred in one SEND/RECEIVE operation using multiple connected channels.
*Input/ Output Contents FLAGS Input Flag (the same as ｺ 0735. Refer to the following table for the details.) TIMER Output Communication monitoring time 001(D) (0.1 second) to 255(D) (25.5 seconds) (Initial value 000(D) is 1 second.) G (7th bit) Output Starting instruction. Turn ON after starting communication. TYPE (0 bit to 6th bit) Output ST1 Output For cases with one hierarchical layer, the number of the target station is 00 to 77(8).
In case of writing 8 bytes data to slave station 03 Module number installing own station JW-20CM : 2 Channel number using own station JW-20CM : 0 Sending data top address of own station : ｺ1000 (file 0, file address 001000(8)) Data area of target station : 09000 (file 0, file address 004000(8)) Top address of communication information storage area : ｺ1100 Own station register Sending data ｺ1000 ｺ1001 ｺ1002 ｺ1003 ｺ1004 ｺ1005 ｺ1006 ｺ1007 CH0 Port No.
9-3 Data transfer required time and communication delay time (1) Required time for data transfer This is the time required for the master station to complete communication with all stations, and is determined by the number of connected stations with and the number of data items to transmit. Transmission T operation cycle = N + 136 × P 1250 + 2.5 × P + α + 16 (ms) N : Total number of link points (value to be calculated by relay link bytes and register link bytes 8 points).
(2) Communication delay time The communication data on the satellite net may have the delay shown below. PC00 ON ① ② I/O PC00 JW-20CM PC01 ;; ;; ;; ;; Operation cycle JW-20CM PC01 ;; ;; ;; ;; ③ ;; ;; ④ ;; ;; ;; ;; ;;; ;;; (Communication) ;; ;; ⑤ ;; ;; I/O ⑥ ;; ;; ⑦ ON ① ② ③ ④ ⑤ Delay of input module Time required for PC to detect input state (one operation cycle max.
(3) Data transmission between master PC and slave PC Providing synchronous transfer gives positive data communication. [An example of synchronized transfer by OUT instruction] Master station (PC00) Slave station (PC01) ｺ 0200 ｺ 0200 ｺ 0203 ｺ 0203 ： Send Program in master station 00000 F–44 02030 : Receive Program in slave station 02000 02000 02030 02000 • 00000 is turned “ON” at the master station side. (OUT 02000 is a self-holding circuit.
9-4 Expansion of network The JW-20CM can transmit data between 64 stations at maximum. If more than 64 stations are required for data link, you can add communication stations with the procedure below. (1) Multiple installation of the JW-20CM Mounting more than one JW-20CM on the optional slot of the basic rack panel can increase the number of stations.
(2) Hierarchical link When 2 sets of JW-20CM are mounted on the optional slot of the basic rack panel, hierarchical link communication is possible and can increase the number of stations.

④ Monitor operation condition by each station PC By creating a program having the flags shown below in each station’s PC, the JW-20CM can monitor the operation condition of each station’s PC. [Ex.
(3) Error code When an error occurs in the JW-20CM, it stores the occurred error’s code to system memory #170 of each station’s PC.
• When any of errors “01(H)” to “18(H)” occurs among the error codes listed on the previous page, the JW20CM stores error code “53(H)” (optional error) in the system memory #160. It does not store any error code in system memory #170. • In the case of an option error "53," when you monitor system memory #050, the bit of error option module switches ON. When more than 1 bit is error, these bits switch ON. The each ON bit becomes OFF by recovering from the error condition.
(4) Recovery method at communication errors ① Check flow chart Occurrence of error Connection status of cable/connector are normal. NO See “Check cable/connector” on next page. YES See “During initial communication” on page 9·66. YES First communication? NO NO Does the error occur continuously? See “When the communication error occurs instantaneously ” on page 9·69. YES 9 See “When the communication error occurs continuously” on page 9·69.
② Check cable/connector As errors on the junction from the main cable to the drop cable or the contact failure on the connecting point of each station or errors of the master module are assumed, check with the following procedure. FAULT lamp turns ON YES Exchange master module NO Monitor “individual communication flag” in support tool.
• If the bus cable between the slave station 05(8) and 06(8) is disconnected in the following system. 03(8) 02(8) 01(8) 04(8) Master station 05(8) B C D Disconnection A 06(8) 07(8) State of an individual communication flag D7 6 5 4 3 2 1 D0 OFF Unstable OFF Remove the connector on point A, and turn ON the termination resistance of the master station. As the communication possible stations 03(8), 02(8), 01(8), and 04(8) are normal, the state of communication monitoring flag is as follows.
③ During initial communication (start-up of the system) Lighting error code 6F(H) · When the master station indicates error code 6F(H) and the COMM lamp is OFF. The cause may be a parameter setting error of the master station. Check the master station parameters below.
· When the master station is normal and the error code 6F(H) of a slave station lights. The cause may be a faulty setting of the slave station parameter. Check the following slave station parameters. Parameter address(8) Contents Setting range 007720, 007721 Relay link receiving bytes of slave station 0 to 256D) Total : 256 max. In case of "0", same as number of sending bytes 007722, 007723 Register link receiving bytes of slave station 0 to 2048(D) Total : 256 max.
Other cases • • • • Check the switches of the JW-20CM (see check item) Check optional cable of PC (The JW-20CM does not operate normally without an optional cable.) Check cable and connector (see check item) Check error code [Switches required check in the JW-20CM] ① Station number (STA NO.) ② Mode switch (MODE) ③ Termination resistance switch (LT) ④ Shield ground switch (LG) If there are errors in the station number and the mode switch, change the setting with the power OFF, and then turn ON the power.
④ When the communication error occurs instantaneously. Cause may be: • Noise on the communication line. • Fault of a communication module. • Fault of a communication cable. Check the error’s timing. When the error occurs synchronous with a peripheral industrial robot’s operation, noise to the communication line may be a cause. Consider arrangement of the wiring route. Identify the error station. When the error occurs at only the specific station, the cause may be the station or nearby.
