(4) Error flag assignment (address: 0005
H
)
Error flag (RXA) is assigned to the remote output (RY) of the extension output module using the external signal
assignment function. When a moderate or major error occurs, the assigned remote output (RY) turns on.
(a) Setting range
The remote output (RY) number of the extension output module, counted from the start remote output (RY)
number (0000
H
) of the main module, is set.
Ex.
The following is an example for assigning Error flag (RXA) to the remote output (RY) number, 4
H
, of the
extension output module.
The remote output (RY) number, 4
H
, is 24
H
when counted from the start remote output (RY) number of
the main module.
Thus, set 24
H
for Alert output signal assignment (address: 0004
H
).
(b) Enabling the setting
Turn on and off Initial data setting request flag (RY9).
(c) Default value
The default value is set to No assignment (FFFF
H
).
If a value out of the setting range is set, an error occurs. The error code (0173
H
) is stored in Latest error code (RWr0), Error
flag (RXA) turns on, and the ERR. LED turns on. The operation is performed in the previous setting.
