•
Remote expansion module
•
Time for inputs R1 to R12: 80 ms + 1 cycle.
•
Time for outputs S1 to S6 (S8): 40 ms + 1 cycle.
Monitoring the functionality of the expansion unit
If the power supply of the expansion unit is not present, no connection can
be established between it and basic unit. The expansion inputs R1 to R12,
R15, R16 are incorrectly processed in the basic device and show status 0.
The outputs S1 to S8 in the expansion device cannot be set.
The status of the internal input I14 of the basic device signals the status of
the expansion unit:
•
I14 = 0: expansion unit is functional.
•
I14 = 1: expansion unit is not functional.
Example:
The expansion unit may be powered up later than the basic unit. This means
that the basic device is switched to RUN when an expansion unit is missing.
The following easy800 circuit diagram detects if the expansion unit is ready
for operation or not functional.
Figure 217:Circuit diagram for expansion testing
As long as I 14 is 1, the remaining circuit diagram is skipped. If I 14 is 0, the
circuit diagram is processed. If the expansion unit drops out for any reason,
the circuit diagram is skipped. M 01 detects whether the circuit diagram was
processed for at least one cycle after the voltage supply is switched on. If
the circuit diagram is skipped, all the outputs retain their previous state.
DANGER
Ensure the continuous monitoring of easy800 expansion units in
order to prevent switching faults in machines or systems.
