(4) Error flag assignment
Error flag (RXA) is assigned to Remote output (RY) of the extension output module using the external signal
assignment function. When a moderate error or major error occurs, the assigned Remote output (RY) turns on.
(a) Setting range
With the head of Remote output (RY) of the main D/A converter module as a starting point (0000H), set the
device number for Remote output (RY) of the connected extension output module.
Ex.
When Error flag (RXA) is assigned to Remote output (RY) numbered 4H as counted from the head (0H) of
the extension output module
Remote output (RY) numbered 4H as counted from the head of the extension output module corresponds to
Remote output (RY) numbered 24H as counted from the head of the main D/A converter module.
Thus, set 24H for Error flag assignment (address: 0005H).
(b) Enabling the setting
Turn on and off Initial data setting request flag (RY9) to enable the setting.
(c) Default value
The default value is No assignment (FFFFH).
(d) Remote buffer memory address
The remote buffer memory address of this area is as follows:
Setting a value out of the range results in the error code (0173H) being stored in Latest error code (RWr0), Error flag (RXA)
turning on, and the ERR. LED lighting up, with the previously set operation.
