■ Communications Parameters
The E5CN/AN/EN/GN’s communications specifications are set in the
communications setting level. These parameters are set on the E5CN/
AN/EN/GN’s front panel. The following table shows the communications
parameters and their setting ranges.
Highlighted values indicate default settings.
Note: The communications data length for Modbus must be 8 bits.
● Communications Parameter Setup
Before you carry out communications with the E5CN/AN/EN/GN, set up
the communications unit number, baud rate, and other parameters by
carrying out the following procedure. For details on operations other
than communications parameter setup, refer to the E5CN/E5AN/E5EN/
E5GN Digital Temperature Controllers User's Manual Basic Type (Cat.
No. H156) for the devices being used.
1. Press the O Key for at least three seconds to move from the
“operation level” to the “initial setting level.”
2. Press the O Key for less than one second to move from the “initial
setting level” to the “communications setting level.”
3. Select the parameters as shown below by pressing the M Key.
