Interroll MultiControl
Initial startup and operation
34 Version 2.3 (01/2017) en-US
Translation of original instruction manual
System status
The fourth area of the process image of the inputs contains the following status information of
the system: the current level of both supply voltages, the temperature and the runtime since the
last restart.
Designation BYTE Data type Comment
Voltage 1 16 INT [mV] supply voltage "Power Motor"
Voltage 2 18 INT [mV] supply voltage "Power Logic+Sensors",
a value is also output here if the second
voltage supply is not connected.
Temperature 20 INT [d°C] temperature of MultiControl
SystemUpTime 22 LINT [s] time since last restart
Additional signals
The last part of the process image of the inputs is subdivided into five subsections:
• Control inputs
• Control outputs
• Handshake signals
• Zone status
• Global signals
These input signals have no meaning for the use of MultiControl as I/O device.
Process image of the
outputs
The process image of the outputs is divided into three parts: Digital I/O, Motors and Other
signals.
Digital outputs
The digital outputs are located in the first part process image of the outputs. The outputs can be
directly switched by a PLC only if the I/O is set to "2: PLC-Output". The physical state at the
output also depends on the configuration of the output (PNP/NPN, positive or negative polarity).
Designation BYTE Bit Data type Comment
I/O 1 0 0 BOOL Output "I/O 1"
I/O 2 0 1 BOOL Output "I/O 2"
I/O 3 0 2 BOOL Output "I/O 3"
I/O 4 0 3 BOOL Output "I/O 4"
Reserve 0 4 BOOL These four bits are currently not in use.

Motors
The second part of the process image of the outputs contains the outputs for the reference
setting of the connected motors.
