O3M
CAN
PLC
Description of the devices and interfaces used:
Number
Function
Description
1
Programmable controller
(e .g . CR0403)
The programmable controller converts the 12-bit CAN value to a physical output .
2
CAN interface
The CAN interface transmits the analogue value (distance) in 12-bit resolution .
3
Device (e .g . O3M251)
The device returns the analogue output value . The output values (distance) are scaled
to the value range 0 . .1 ("0" corresponds to a distance of
≤
0 m, "1" corresponds to a
distance of ≥ 10 m).
15.13 Description of the switches "Enable CAN output"
In the "Enable CAN output" selection area, switches for signal transmission via the CAN interface are
displayed . To keep the bus load low, a maximum of 3 CAN messages (size: 64 bits) are sent . The
switches each activate one of the CAN messages .
Each switch activates a fixed set of outputs:
●
Switch 1: digital 0 - 37 and analoge 0 - 1
●
Switch 2: digital 38-99
●
Switch 3: analogue 2-5
Keep the bus load of the CAN interface as low as possible .
►
Only activate the necessary digital or analogue outputs via one of the switches .
The CAN interface is described in a separate CAN document .
15.14 Description of the "Logic teach commands"
In the "Logic teach commands" selection area, commands for triggering and deleting signals are
displayed .
The "Logic teach commands" simulate a signal for storing information with the "Teach" module:
●
[Teach] button: The signal for storing information with the "Teach" module is triggered .
●
[Reset] button: The memory contents of the "Teach" module are deleted .
The "Logic teach commands" can be found at the end of the selection list
