4. Installation
Montage
The M1400 is connected to the fibre optic ring using fibre optic connections (Toshiba). The
maximum length of the FO cable, leading to the neighbouring boxes, should not be more then
600m for glass fibre or 45 meters for other fibres. These values are only valid if for bending
the cable a radius of at least 30 mm is used. If there are no glass fibres used, no special tools
are needed for installation of the plugs.
Common actors and sensor are connected directly to the inputs / outputs (using"+,-,signal" ).
The M1400 is installed at the machine or simply by installing it to a cartridge carrier
according to DIN EN 50022 or DIN EN 50035.
Configuration
Each I/Oport of the M1400 can be configured as input or as output. This does not dependent
on the configuration of the other ports. There are DIP switches under the XILINX board of the
M1400. In order to change the state of the switches the module’s cartridge has to be opened.
The DIP switches are assigned as follows:
switch 1 => port D0
switch 2 => port D1
switch 3 => port D2
switch 4 => port D3
It depends on the state of the switch whether a port is an output or an input :
’ON’ => port is output
’OFF’ => port is input
ATTENTION:
Configuring a port as input ( switch "OFF") all of the eight output controller
ICs of the port concerned have to be removed.
If the ICs are not removed the port is not functional as input, but the module
remains undamaged.
