M1400
About the Hardware
The parallel module M1400 is an input / output module used in the II/O system. There are 32
Standard 24 V inputs / outputs, which achieve 4 ports of 8 bit each.
These 4 ports ( D0..D3 ) correspond to the data bytes in the FO transmissions protocol and
according to the way they are to be used, they can be configured as input or output.
Each input / output has an LED, that indicates the current state. Furthermore there are three
LED’s installed used for diagnosis of the II/O fibre optical ring:
LD1 The green ’CYCLE’ LED is switched on by each start bit of a telegram and is
switched off again by the stop bit.
LD2 The red ’ERROR’LED is switched on after the recognition of a bad telegram (checksum,
frame). After a sequence of three correct telegrams (checksum, frame) were processed it
is switched off again.
LD3 The green LED ’WATCHDOG’is switched on by a valid writing telegram with matching
address. If no telegram with the properties defined above is recognised for the next
100 ms a special unit of the module switches off all outputs.
In case an error is detected, all outputs are reset.

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.

View under the M1400 XILINX board
The following module configuration is possible by setting jumpers 1 to 3 :
Jumper 1 Watchdog on / off
for Port D0 and D1
If this jumper is set the ’Watchdog’function is switched off.
This means if an error is detected the outputs set of Port D0
and D1 are not switched off.
Jumper 2 Watchdog on / off
for Port D2 und D3
If this jumper is set the ’Watchdog’function is switched off.
This means if an error is detected the outputs set of Port D2
and D3 are not switched off.
Jumper 3 Latch on / off
standard configuration is jumper ’set’
input are latched in intervals of 6,8 ms
otherwise inputs are latched permanently

The following modul configuration is possible by setting jumpers 4 to 7 :
Fast Inputs M1400 (Interrupt Inputs)
Jumper 4 Fast input II3 :
If jumper connection betwenn port D0.3 and XILINX II3 is
established Fast input is activated
Jumper 5 Fast input II2 :
If jumper connection betwenn port D0.2 and XILINX II3 is
established Fast input is activated
Jumper 6 Fast input II1 :
If jumper connection betwenn port D0.1 and XILINX II3 is
established Fast input is activated
Jumper 7 Fast input II0 :
If jumper connection betwenn port D0.0 and XILINX II3 is
established Fast input is activated
Power Supply
There are the following connections for power Supply :
(1) two pole plug connection for the controller (X10 Pin1+2)
(2) two pole plug connection for outputs (X20 and X30 Pin1+2)
( 16 outputs )
(3) two pole plug connection for inputs (X21 and X31 Pin1+2)
(16 inputs)
(4) two pole plug connection for ground (X22 and X32 Pin1+2)
