Error Alarm Relays (E) - Panasonic FP-E Programming Manual

1.2.11 Error Alarm Relays (E)

Note
Error alarm relays can only be used with the FP2SH/FP10SH.
Function of error alarm relays (E)
Error alarm relays are used to feed back error conditions freely assigned by the user
to internal relays, and to store them in memory.
Error alarm relays are turned on and off using the SET and RST instructions in the user
program.
When an error alarm relay goes on, the number of error alarm relays which are on, the
relay numbers, and the data of the calendar timer which went on first are stored in a
memory area in the CPU unit.
DT90400
DT90401 to DT90419
DT90420
DT90421
DT90422
Information for up to 500 error alarm relays can be stored in the memory area. Those
which can be monitored or operated by the user, however, are those in the range from
DT90401 to DT90419 only.
Usage restrictions and precautions
Error alarm relay (E) cannot be specified as the output destination for the OT, KP, or ALT
instructions.
Error alarm relay (E) can be turned on and off in multiple locations in the program, using
the SET and RST instructions. However, no check is carried out for overlapping use.
Program for setting (turning on) an error alarm relays
The SET instruction should be used to turn on error alarm relays in the error alarm
conditions.
Error alarm relays are held even if the error condition goes off.
