51.13 RS484 SERIAL CONNECTION
The XJ485CX interface is a signal converter (from TTL to RS485). The RS485 uses two terminals (+) and (-)
that must be connected respecting the polarity.
Use the CAB/RS02 to connect the XJ485 interface to the TTL connector.
52. I/O EXPANSION CONNECTION
Through the I/O expansion is possible to increase the number of probes, digital inputs, relay and analog
outputs.
The I/O expansion does not regulate independently but is only an actuator; the configuration of the inputs
and outputs must be made through EI parameters in the IC200D EVO map.
The connection diagrams of the I/O expansion are shown in the manual of the expansion.
The connection to the Ichill is done via LAN.
To configure the expansion is necessary to:
• enable expansion presence via parameter CF78 "Presence expansion card I / O"
• configure the address of communication with the iCHILL with parameter EI01
• configure expansion ICX207D the communication address via dip-switch, which must match the address
set in parameter EI01 of the Ichill
• configure the inputs and outputs using the parameters EI02...EI43 of the Ichill
• connect the iCHILL and expansion according to the diagram showed below
In case of lack or loss of LAN communication, adjustment dell'Ichill is immediately blocked.
The maximum length of the LAN connection is 30 mt.
The address of LAN communication with the controller iCHILL EVO series must be set via dip-switch.
