2.3
Operation
●
The unit is operated via an operator panel in the front door of the device.
●
The device signals an
uncertain operating state
with status indicators (
The device remains in Measuring mode.
●
Should a
malfunction
occur, the device switches automatically to “Stand-By” (
).
– The sample gas line and the sample gas path in the device are automatically purged
with instrument air in this mode.
If a test gas generator CALSIC300 is used: Test gas generator and vaporizer are also
purged.
– The analog outputs remain at the last valid measured value.
2.3.1
Operation via SOPAS ET (option)
Operator menus and measured value displays are also available on an external PC via the
Ethernet connection (with the SOPAS ET engineering tool
).
2.4
Interfaces

●
4 x digital inputs
●
4 x digital outputs
●
1 x Ethernet interface
More interfaces depending on configuration (refer to “Documentation of individual set-
tings”).
2.5
Remote control
2.5.1
Ethernet
Standard: Ethernet (Modbus TCP/IP).
2.5.2
Modbus
Modbus
®
is a communication standard for digital controls to connect a »Master« device
with several »Slave« devices. The Modbus protocol defines the communication commands
only but not their electronic transfer; therefore it can be used with different digital inter-
faces (Ethernet).
2.5.3
OPC (option)
OPC is a standardized software interface that allows to exchange data between the appli-
cations of different manufacturers.
The SICK OPC server is required.
System bus: Ethernet.
