7-3 Allocation of relay numbers
Relay numbers for the input, output, special, and option modules are stored in the control module of the
JW300 system for each rack and each slot, depending on the type of modules installed.
There are two method to register relay numbers: 1) Automatic I/O registration by turning ON the power to
the modules (does not need any support tool), 2) Manually enter I/O addresses using a support tool.
- Auto I/O Registration when the power is ON
When the PROTECT switch on the control module is OFF, and system memory #0247 = 00
(H)
, the relay
numbers will be registered automatically if the power is turned ON. After the Auto I/O Registration, turn
OFF the PROTECT switch, or make #0247 = 03
(H)
, to prohibit further Auto I/O Registration.
- I/O Address Setting using a support tool
I/O addresses can be registered from a menu by using the JW-300SP or JW-15PG. For details about
their operation, see the respective user's manual.
Using the JW-15PG, you can only perform an Auto I/O Registration. You cannot perform Free I/O
Address Setting.
- The JW300 verifies the registered relay numbers whenever its mode changes (from stop to run). After
verifying them, if the numbers do not match the modules actually installed, the FLT lamp on the control
module will light. The JW300 stops operation, and stores the error code 60
(H)
(table verification error) in
system memory #0160.
[1] Setting I/O addresses
The JW300's I/O addresses can be set using Auto I/O Registration, Free I/O Registration (continuous
allocation), and Free I/O Registration (individual allocation).
