The E5CN/AN/EN-HT's communications specifications are set in the commu-
nications setting level. These parameters are set on the E5CN/AN/EN-HT's
front panel. The following table shows the communications parameters and
their setting ranges.

Note: The communications data length for Modbus must be 8 bits.
Before you carry out communications with the E5CN/AN/EN-HT, 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 E5CN/AN/EN-HT Digital Controllers Program Type
User's Manual (Cat. No. H169) for the devices being used.
