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 communications with
PLCs. No communications programming is required.
Number of connected Digital Temperature Controllers:
32 max. (Up to 16 for the FX Series)

When Digital Temperature Controllers are
connected, set points and RUN/STOP
commands can be sent from the Digital
Temperature Controller that is set as the
Component
master to the Digital Temperature
Communications *1
Controllers that are set as slaves.
Slope and offsets can be set for the set point.
Number of connected Digital Temperature
Controllers: 32 max. (including master)
When Digital Temperature Controllers are
connected, the parameters can be copied

from the Digital Temperature Controller that is
set as the master to the Digital Temperature
Controllers that are set as slaves.

*1. A Temperature Controller with version 1.1 or higher is required.
A Temperature Controller with version 2.1 or higher is required for
the FX Series or the KV Series.
*2. Both the programless communications and the component
communications support the copying.

*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.
