Chapter 7: Wiring Method 7-1 Cable trunk and branch lines On the illustration of the cable wiring below, a bold line means a trunk and the thin lines branched from the trunk with a "T" shape are called branch lines. Branch line 400mm max. Trunk cable The length of branch lines branched from the trunk should be within 400 mm. 7 400mm Branch line Trunk cable Total cable length should be within 1 km. 7-2 Relaying of trunk cables To relay trunk cables, use the straight joint (ME-JJ-01).
7-3 Cable wiring procedure in control panel (1) Fixing of the cable In order not to put any force on the cable and the JW-21MN, fasten the cable to an line nearby input of a control panel or a "T" branch point to the JW21MN using saddles etc. JW-21MN Saddle Saddle (2) Extra length of cable Provide an extra length of the cable of 2 to 3 m inside a control panel for easier processing of the cable end and easier wiring when changing module positions.
(6) Bending radius of the signal cable should be less than 45 mm (outside). R4 5 or la rg er - Specification of the cable manufacturer is that bending radius should be 6x of the cable finish outside diameter (approx. 7.5 mm). (7) When you install morethan one module of the JW-21MN into one programmable controller, we recommend to put identification tag on each dable. 7 (8) Before transport or store the JW-21MN, put a protection cap on the connector of the JW-21MN.
7-4 Waterproof and insulation processing of connectors In order to prevent water intrusion into the "T" branch connectors and the straight connectors, we recommend to wind a self-adhesive tape and provide waterproof processing for them. For insulation purposes, cover these connectors with jackets. (1) "T" branch connector To wind a self-adhesive tape, cut the tape at about 10 cm each and start winding from position Start winding cut tapes from and as well.
7-5 Wiring of cables at outside control panels Do not bundle the coaxial cable (the trunk and branch lines) together with power cables, and separate from power cables at least by 100 mm. Do not put the coaxial cable into a power line wired duct. The best way is to put the communication line in an independent duct. Be careful that the coaxial cable does not receive any load by laying under a heavy weight such as other cables.
7-7 Wiring method for adding a communication station (1) Branching method When branching a line for an additional station, be sure to branch from the trunk using a T connector. Never branch from a branch line.
(3) Notes When adding a communication station, follow the items below. No. 1 2 3 4 5 6 Item Branch from the trunk cable. Don’t use the same station number twice. Check the termination resistance switch. Provide extra length for the expansion cable. Do not exceed the 1 km limit for total length of the cable. Change the layout drawing for installation. Reason Another branch line from a branch line may not give appropriate communication by reflection wave.
Chapter 8: Memory Address on the ME-NET The ME-NET employs a system for addressing individual memory banks in all of the connected equipment by allocating address throughout the ME-NET. Therefore, the top address in any link area which will contain in the data link parameters and memory addresses used for computer link instructions must be a valid memory address in the ME-NET. The relationship between memory addresses in Sharp PCs (JW20/JW20H/JW30H) and those on the ME-NET are shown below.

Chapter 9: Description for Data Link Operation The data link function is used to send and receive ON/OFF signals (relay link) and data (register link) between modules by assigning one module from PCs or FA devices as the master station and other units as slave stations in the satellite net system. Up to 64 sets of PCs and FA devices can be connected in the satellite net. Each station sends data in its sending area cyclically and stores data received from other stations in its receiving area.
(2) Register link 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.
9-2 Required transmission time and communication delay time [1] Required transmission time 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. N + 136 × P + 2.5 × P + α + 16 (ms) 1250 N : Total number of link points (value to be calculated by relay link bytes and register link bytes 8 points).

12-3 Storage of error code When an error occurs in the JW-21MN, it stores the occurred error’s code to system memory #160, #170 and error history storage register of each station's PC.
(1) System memory #170 to 177 (option module error code) 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-21MN recovers from the error.
(4) Error history When the JW-21MN has errors, it stores them in an error history register. The storage area is specified using the module No. switch setting value. Error history storage register Module No.
