3.2 Port J26 con guration
Compared to the pCO5, pCO5+ controllers are provided with 4
microswitches for con guring serial port J26 ( gure):
• microswitches all down: port J26 set with Fieldbus hardware;
• microswitches all up: port J26 set with BMS hardware*.
Factory con guration: Fieldbus port.
(*) The serial port remains the FieldBus2 at software level within the
development environment.

3.3 Controller network connections
The pCO5+ comes with three kinds of serial ports: pLAN, Fieldbus, BMS.
The RS485 Fieldbus serial port is designed with Main-type hardware,
while the RS485 BMS serial port has Secondary-type hardware. The
protocols used on the RS485 Fieldbus port are, due to the nature of
the port, Main protocols (CAREL Main or Modbus RTU Main), although
in special cases Secondary protocols can be used (CAREL Secondary or
Modbus RTU Secondary), adopting the necessary measures. Likewise,
Secondary protocols are applied on the RS485 BMS port, although under
certain conditions Main protocols can also be used.
Notice: The pLAN network is multi-Main, meaning that each
controller can work as Main or Secondary at the same time.

Important warnings:
• By applying the appropriate impedance, a serial port with Main (FBus)
hardware supplies the network with the bias voltage required to run all
the connected devices, i.e. the Main itself and its Secondaries.
• Conversely, serial ports with Secondaries hardware (BMS) do not provide
bias voltage, so it is always advisable to connect at least one device with
Main hardware (FBus) to the network so that it is correctly biased.
• However, no more than two devices with Main hardware (FBus) can
be connected to the same network, otherwise the network’s total
bias impedance becomes too small and incapable of supplying the
required voltage to the RS485 network.
• We recommend connecting the serial probes or other eld devices to
an optically-isolated version of the Fieldbus serial port or to serial port
TWO – Fieldbus 1 to exploit the ltering properties of optical isolation.
Special cases
• In networks consisting only of Secondary HW devices, no more than
207 devices can be connected. The max. length allowed for the
network is 100 m.
DO NOT connect the 120Ω, 1/4W terminating resistors to the rst
and last devices;
• In networks consisting only of Main HW devices, no more than 2
devices can be connected. The max. length allowed for the network
is 1000 m. If the network is longer than 100 m, apply the 120Ω, 1/4W
terminating resistors to the rst and last devices in the network;
• connect the computer to a network with no more than 1 Main HW
device or no more than 207 Secondary HW devices.
