7-2 Allocation of the relay number
Relay numbers of input, output, special, and option module are assigned by automatic registration when
the power source is turned ON (protect switch: OFF), or by I/O registration (automatic registration/table
creation) of the support tool (corresponding to JW-32CUM1).
As the assignment, relay points are registered in the control module of JW-32CUM1, by the type of the
mounting module, in every rack and slot number of the basic and expansion rack panel.
When the protect switch of the control module is OFF and the system memory #247 = 0, the relay
numbers are assigned automatically when the power source is turned ON. After automatic registration,
prohibit automatic registration during operation by turning ON the protect switch or writing #247 = 03
HEX
.
The registered relay number is verified by self-diagnosis when changing the mode of JW30H (JW-
32CUM1) (starting operation from stopped state). As a result of verification, if different from the mounted
module, the FLT lamp of the JW-32CUM1 control module lights, and the JW30H (JW-32CUM1) stops
operation. At the same time, the error code 60 (table verify error) is stored in the system memory #160.
[1] Kinds of I/O registration
I/O registration of JW30H (JW-32CUM1) have "Auto registration" and "Table creation."

Max. number of I/O points and I/O relay area.
Note 1: When some other control module in the JW30H series is used (such as the JW-
33CUH1), the first rack number address must be "ｺ0000" and the others are numbered
sequentially.
Note 2: The I/O mounted on the remote I/O slave station JW-21RS is not registered
automatically.
- When the JW-32CUM1 remote I/O master station function is used, and a JW-21RS is
used as a slave station, register the slave station I/O as a remote I/O parameter on the
JW-32CUM1.
- When the master station is JW-21CM and the slave station is JW-21RS, the I/O
registration of slave station is registered in the parameter of JW-21CM.
