Chapter 3 CONFIGURATIONS
3.3.4 Parameter data
During initialisation, the EH-IOCP identifies all installed IO modules. These identities are compared with the parameter
data received from the master during parameterisation of the EH-IOCP Profibus-DP slave node.
If a mismatch is found in one or more identities, the parameterisation of the node is rejected and the node will not go on-
line.
The parameter data shown in table 6 must therefore be set by the user according to the current slave rack configuration.
The first byte is reserved and must be 0x00. In the following 16 bytes, the identities of the installed IO modules found in
table 1, chapter 2.3 are to be set.
All 16 slots ( eight slots in the basic base and eight slots in the optional expansion base) must be assigned an module ID,
even the empty slots.
The user data length must therefore always be set to 17.
