The P CE-IR 56
PCE Instruments infrared temperature sensors.
The P CE-IR5 6 functions as the Modbus Master on an RS485 network of up to 6 temperature sensors,
and can itself be connected as a slave device to another RS485 network via a second, isolated
Modbus interface. This allows multiple P CE-IR5 6 units to be multi-dropped to create a large network
of sensors and displays.
Optional alarm relay modules allow the P CE-IR5 6 to be connected to alarm equipment such as
sounders and beacons, and optional analogue output modules allow it to be connected to non-
Modbus instrumentation.
modules are adjustable via the PCE-IR5 6 built-in resistive touch screen interface, which can be
operated even with gloves on.
With an optional MicroSD Card inserted, the P CE-IR5 6

manually started and stopped via a button on the temperature display screen, or scheduled to
begin at a pre-determined time via the Settings menu.
If the PCE-IR 56 is connected via the slave interface to another Modbus network, logging may also be
started remotely by the Modbus Master on that network.

The PCE-IR 56 has removable screw terminal blocks for the Modbus Slave and Modbus Master
interfaces.
− Connect the Master interface to the sensors and output modules. Be sure to check the power
supply requirements of each device before applying power.
− Optionally, connect the Slave interface to another Modbus network with its own Modbus
Master such as a PLC or SCADA system.
Isolation is provided between the Slave and Master interfaces.
MICROSD CARD AND BATTERY
The MicroSD Card and battery slots are located on the touch screen circuit board. Unscrew the lid
of the PCE-IR 56 to access them.
The battery is optional. With a battery tted, the internal clock will continue to run when the power
is o. Without a battery, the unit will request the date and time each time the power is cycled.
All other settings are stored in the unit’s permanent memory and will be preserved when it is
switched o, regardless of whether a battery is tted.

See sensor manual for further details.
Notes:
1. For further information please refer to http://www .modbus.org/specs.php
2. Use address 255 to communicate with any connected unit (only one sensor connected)
3. Use address 0 to broadcast to all connected units (no response expected)
