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.
Number of connected Temperature Controllers:
32 max. (Up to 16 for the FX Series)
Programless
Applicable PLCs

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

Copying 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.
