Communications Functions
You can use the memory in the PLC to read and
write E5@C parameters, start and stop operation,
etc. The E5@C automatically performs communi-
cations with PLCs. No communications program-
ming is required.

*1 For heater burnout alarms, the heater current will be measured
when the control output is ON, and the output will turn ON if the
heater current is lower than the set value (i.e., heater burnout
detection current value).
*2 For SSR failure alarms, the heater current will be measured when
the control output is OFF, and the output will turn ON if the heater
current is higher than the set value (i.e., SSR failure detection
current value).
*3 The value is 30 ms for a control period of 0.1 s or 0.2 s.
*4 The value is 35 ms for a control period of 0.1 s or 0.2 s.
