About the Hardware
The parallel module M1600 is an input / output module used in the II/O system. There are 16
Standard 24 V inputs / outputs and 8 high current outputs, which achieve 3 ports of 8 bit
each.
These 3 ports ( D0..D2 ) correspond to the data bytes in the FO transmissions protocol and
according to the way they are to be used, the ports D0 and D1 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.
