Communications Specifications
*
The baud rate, data bit length, stop bit length, and vertical parity can
be individually set using the Communications Setting Level.

Heater Burnout Alarms and SSR Failure
Alarms
*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 38 ms for a control period of 0.1 s or 0.2 s.

communications
You can use the memory in the PLC to read and write
E5CD-800/E5CD-B-800 parameters, start and stop
operation, etc. The E5CD-800/E5CD-B-800
automatically performs communications with PLCs. No
communications programming is required.
Number of connected Digital Temperature Controllers:
32 max. (Up to 16 for the FX3)
Applicable PLCs
OMRON PLCs
CS Series, CJ Series, CP
Series, NJ Series, or NX1P
Mitsubishi Electric PLCs MELSEC Q Series, L Series,
FX3 Series, or iQ-R Series
KEYENCE PLCs KEYENCE KV Series
Copying
*
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.
