erial communication and programming
Communication between the c.pCO Medium and its built-in driver
is managed internally through the FBus2 serial port. The FBus2 serial
port (J26) is however electrically isolated from the driver serial line; this
ensures that in case of external faults on the line connected to FBus2,
the internal driver can keep on working independently. The driver can
only be configured using the c.pCO application developed with c.suite;
no external display is available for the driver.
The c.suite development environment features a module for managing
the EVD Evolution driver. When managing the built-in driver, use the
module as if managing an external driver connected to the FBus2 port.
At a c.suite application software level, the valve driver must be connected
to the FBus2 port. Consequently, any other devices physically connected
to the Fbus2 port (J26) must have the same communication protocol
(CAREL Standard Master or Modbus® Master), the same baud rate, stop
bits and parity. The built-in driver address is 198 (EVD Evolution default
address), so any other devices connected to J26 must have an address
other than 198. Communication frame configuration is performed
by using c.suite environment. External EVD Evolution drivers can be
connected to the Fieldbus1 serial port (optional card) with no address
restrictions.

Important:
to ensure efficient data exchange between the driver
and the controller, when developing the c.suite application, if there are
devices connected to the FBus2 port (terminal J26) using the Modbus®
protocol, developers should take into account the number of variables
exchanged over the entire serial line.
5.7 Digital
outputs
Electromechanical relay digital outputs
The controller features digital outputs with electromechanical relays. For
ease of installation, the common terminals of some of the relays have
been grouped together. Some relays feature changeover contacts.

The type of insulation is described in the table below. See also the
Technical Specifications table in chap. 12.

Type of insulation
Between relays in group 1 & 2
basic insulation
Between relays in group 3 and in group 1 & 2
reinforced insulation
Note:
•
between groups 1 and 2 there is basic insulation, and these must
therefore have the same voltage (generally 24 Vac or 110/230 Vac);
•
between the relay groups 1 and 2 and group 3 there is reinforced
insulation, and so group 3 can have a different voltage.

reinforced insulation
Note:
•
inside each group, the relays have just functional insulation and must
therefore have the same voltage (generally 24 Vac or 110/230 Vac);
•
between groups there is reinforced insulation, so different groups can
have different voltages.

Important:
the current on the common terminals must not exceed
the capacity (rated current) of each single terminal (8 A).
