* Use a high-power port for the USB port.
Note: A driver must be installed on the computer. Refer to the
Instruction Manual included with the Cable for the installation
procedure.
Communications Specifications
* The baud rate, data bit length, stop bit length, and vertical parity can
be individually set using the Communications Setting Level.

Ratings
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 35 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
E5@C parameters, start and stop operation, etc.
The E5@C automatically performs communications
with the PLC. No communications programming is re-
quired.
Number of connected Digital Temperature Controllers:
32 max.
Applicable PLCs: OMRON PLCs

Communications
between
components *
When Digital Temperature Controllers are connected,
the parameters can be copied from the Digital Temper-
ature Controller that is set as the master to the Digital
Temperature Controllers that are set as slaves.
Number of connected Digital Temperature Controllers:
32 max. (including master)
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
master to the Digital Temperature 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)
