PCCC Object

80119691
PCCC (pronounced "P C Cube") is used in several PLCs from Rockwell Automation/Allen Bradley,
which still continue to be used. It was developed before CIP and EtherNet/IP were defined. PCCC te-
legrams are either:
a) Encapsulated in CIP packages (e.g. via EtherNet/IP)
b) The encapsulation of CIP packages.
The SP-COP2-ENI module supports the encapsulation of PCCC data in CIP packages, as described
above under b). For this, the class ID 0x67 = 103 was specified.
The PCCC commands listed in the following table are supported by the SP-COP2-ENI module.
All PCCC-related data with a size of 16 bits (word) are available in the "Little Endian" format. This
means that the byte with the lowest value is executed first.
