7.7.2 Assignment of Relay Nos. and Data Memory Address Nos.
The KV-L2 can be connected to a device with an RS-232C or RS-422A port to load
consecutive text data (100 bytes maximum) as a batch into its data memory and to
send text data from data memory.
Assigning relay nos. and data memory address nos.
Specify the first relay no. of the internal relays and, from the assigned data memory
addresses (DM9700 to DM9707), specify the first DM no. of the data memory
addresses for transmission/reception of text data.
Port nos. and assigned DM nos.
Ports 1 and 2 access the assigned DM addresses shown in the following table.
■ Designating the first relay no.
• Five relay nos., including the first relay no., are assigned.
• Specify the starting relay no. of the channel (the relay no. with "00" as the two
least significant digits) as the first relay no. Even if a relay in the middle of the
channel is designated as the first relay, the starting relay of the channel becomes
the first relay
Example: When specifying 1710 as the first relay no., relay nos. 1700 to 1704 are
assigned.
• When 0000 is specified as the first relay no., the following relay nos. are as-
signed.
