7 - SUPERVISION

The controller may be connected to a local or remote monitoring PC or to most types of CMS (Modbus). For the listed functions to be
used, optional cards (Rs485, pCO Web) or gateways (devices able to interpret various communication protocols) must be installed
NOTE:
If using a communication bus, the routing and processing of the available data are functions not provided by the manufacturer. They
must be provided by the installer, and require the involvement of an integrator.

7.1 - CMS

Various communication standards can be used to connect with a CMS. Expansion boards are inserted in the "Serial Card" port on the
controller.
Modbus®RTU: insert the RS485 expansion board and connect it as instructed in the manual. Validating the protocol on the user
terminal (screen g1):
- Protocol MODBUS RTU
- Speed ---- bds (Set in accordance with the CMS speed)
- Address 001 (Different to 0)
Modbus® TCP: insert the pCo Web card and connect it as instructed in the manual. Validating the protocol on the user terminal (screen
g1):
- Protocol
MODBUS TCP
- Speed 19200 bds (Mandatory)
- Address 001 (Mandatory)
Bacnet® IP: insert the pCo Web card and connect it as instructed in the manual. Validating the protocol on the user terminal (screen
g1):
- Protocol BACNET IP
- Speed
19200 bds (Mandatory)
- Address 001 (Mandatory)

7.2 - The datapoint database

The unit comes with a communication database that includes the most important datapoints for the program, from the values of the
sensors to the parameters displayed in the masks. The database contains three types of datapoint: digital datapoints, integer datapoints
and analogue datapoints. The tables below list the names of these datapoints, their addresses and types (read-only (R) or read/write
(R/W)).
