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

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).

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).

The value is 30 ms for a control period of 0.1 s or 0.2 s.

The value is 35 ms for a control period of 0.1 s or 0.2 s.

communica-

tions

You can use the memory in the PLC to read and write E5

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)

Applicable PLCs: OMRON PLCs

CS Series, CJ Series, or CP Series

Mitsubishi Electric PLCs

MELSEC Q Series, L Series, or FX Series (compati-

ble with the FX2 or FX3 (excluding the FX1S))

KEYENCE PLCs

KEYENCE KV Series

Component

Communica-

tions

When Digital Temperature Controllers are connected, set

points and RUN/STOP commands can be sent from the Dig-

ital 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)

Copying*

When Digital Temperature Controllers are connected, the pa-

rameters can be copied from the Digital Temperature Control-

ler that is set as the master to the Digital Temperature

Controllers that are set as slaves.
