Ceag Device Support Block (Ceagdsb); I/O Modules Supported By The Ceagdsb - Honeywell Experion PKS User Manual

7.7 CEAG Device Support Block (CEAGDSB)

The CEAGDSB runs on the PGM and represents one PROFIBUS field device in the PROFIBUS network. The
CEAGDSB processes the raw data from the CEAG field devices and converts it to the PDC format supported
by Experion. The CEAGDSB communicates with the master PGM for data conversion.
A single CEAGDSB supports up to 46 I/O modules. The CEAGDSB is used for configuring the CEAG LB/FB
Remote I/O family when using PROFIBUS communication unit Easy COM LB8106/FB8206 V6.XX.
The CEAGDSB supports the I/O stations per bus line that provide 31 stations without repeaters and up to 125
stations with repeaters. The maximum number of modules per slave device is 49 (46 I/O modules plus 3 slots
reserved for the communication unit) in the field network configuration. The communication unit present in
each station transfers the data of internal system bus to the protocols of the master bus system.
The maximum number of PDCs required per station is 48 and this can be interpreted as follows:
• 2 PDCs for the communication unit and 46 PDCs for 46 one-channel modules.
Or
• 2 PDCs for the communication unit and 46 PDCs for 23 multi-channel modules having both inputs and
outputs.
Attention
• The maximum number of one-channel I/O module per station is 46.
• The maximum number of multi-channel I/O module per station is 23.
