  The E5CN/AN/EN are provided with a communications function that enables parameters to be checked and set from a host computer. If the communica- tions function is required, use the E53-CN@03N2 with the E5CN, or the E53- EN03 or E53-EN01 with the E5AN/EN. For details on the communications function, see the separate Communications Manual Basic Type.

  The Protocol Setting parameter is displayed only when CompoWay/F commu- nications are being used. Setting Communications Match the communications specifications of the E5CN/AN/EN and the host Data computer. If a 1:N connection is being used, ensure that the communications specifications for all devices in the system (except the communications Unit No.) are the same.
