Function Codes 25 and 41 – Analog/Digital Input
GENERAL DESCRIPTION
This function can be used to acquire an input (analog, digital or any other data type
supported by the MOD 30ML or Modcell) over the peer-to-peer network ICN
(Instrument Communication Network) from any other member on the network.
UTILIZATION
The MOD 30ML/MODCELL compound FC25 and 41 uses an IC (Input
Communication) block to receive an input over the ICN.
Figure 25 .1.
Function Code 25
EXPLANATION
ICN is a proprietary communication network used for peer-to-peer communication
between the MOD 30 instruments, MOD 30ML, Modcell and the LCP (Local Control
Panel). The ICN allows up to 16 addresses (in most cases 16 instruments) on the network.
Each instrument needs to have a unique address on the ICN (0 thru F). The ICN is updated
every 250 ms.
