The "ZPA mode" contains a zero pressure accumulation conveying logic. In "ZPA
mode", the fieldbus controllers exchange commands between themselves and regard-
less of the higher-level controller.
In "PLC mode", the fieldbus controllers are controlled directly by the PLC.
The access points are explained briefly in the following table. Refer to the chapter "Ap-
pendix"(→230) for a detailed description.
Configuration type Access points Description Bytes
standard configuration ECC-DFC-24-00 Reserved for internal use. 64
ECC-DFC-24-00 in reduced PLC
mode
This access point is optimized for
an I/O length of 16bytes.
16
ECC-DFC-24-00 in reduced ZPA
mode
This access point is optimized for
an I/O length of 30bytes.

full PLC configuration ECC-DFC-24-00 in 4PDW PLC
mode
This access point uses an efficient
profile reduced to 4bytes. As in
PLC mode, the PLC takes full con-
trol of the ECDriveS
