* 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.

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
*1
You can use the memory in the PLC to read and
write E5@C-T parameters, start and reset opera-
tion, etc. The E5@C-T automatically performs
communications with PLCs. No communications
programming is required.
Number of connected Digital Temperature Con-
trollers: 32 max.
Applicable PLCs
OMRON PLCs
CS Series, CJ Series, or
CP Series
Mitsubishi Electric PLCs
MELSEC Q Series, L Series
Component
Communications
When Digital Temperature Controllers are con-
nected, set points and RUN/STOP commands
can be sent from the Digital Temperature Control-
ler that is set as the master to the Digital Temper-
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)
Copying
*1
When Digital Temperature Controllers are con-
nected, 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.
