4. Installation
The M2400 is connected to the fibre optic ring, using fibre optic connectors (Toshiba). The
maximum length of the FO cable, leading to the neighbouring boxes, should not exceed
600m for glass fibre or 45 meters for other fibres. These values are valid only if for bending
the cable a radius of at least 30 mm is used. When using plastic FO, no special tools are
needed for installation of the plugs.
Common actors and sensors are connected directly to the inputs / outputs (using "+,-,signal" ).
The M2400 is installed at the machine or simply by installing it to a cartridge carrier
according to DIN EN 50022 or DIN EN 50035
Configuration
The ports D0 and D1 are used for analog output. D2 and D3 can be configured as input or
output according to the way they are used.
Each I/O port of the M2400 can be configured as input or as output. This does not dependent
on the configuration of the other ports. There are DIP switches used for configuration.
The DIP switches are assigned as follows :
Switch 1 => Port D0 mast always be 'ON'
Switch 2 => Port D1 must always be 'ON'
Switch 3 => Port D2
Switch 4 => Port D3
Depending on the state of the switches, the port is input or output :
'ON' => port is output
'OFF' => port is input
