Description of the frame:
•
Byte 2 and 3: Information on the TOR1
•
If configured as an input (event or Periodic mode): these bytes contain the value of the event counter of Input TOR1
•
If configured as an output: current state of the output TOR1
•
Byte 4 and 5: Information on TOR2
•
If configured as an input (event or Periodic mode): these bytes contain the value of the event counter of Input TOR2
•
If configured as an output: current state of the output TOR2
•
Byte 6 and 7: Information on TOR3
•
If configured as an input (event or Periodic mode): these bytes contain the value of the event counter of Input TOR3
•
If configured as an output: current state of the output TOR3
•
Byte 8 and 9: Information on TOR4
• If configured as an input (event or Periodic mode): these bytes contain the value of the event counter of Input TOR4
• If configured as an output: current state of the output TOR4
•
Byte 10: Details: detailed information on the states of the TORs:
• <0> TOR1: Current state
• <1> TOR1: State at the sending of the previous frame
• <2> TOR2: Current state
• <3> TOR2: State at the sending of the previous frame
• <4> TOR3: Current state
• <5> TOR3: State at the sending of the previous frame
• <6> TOR4: Current state
• <7> TOR4: State at the sending of the previous frame
In the example in grey this gives:
•
Byte 2 and 3=0X00F1: value of the event counter of input TOR1 equal to 241
•
Byte 4 and 5=0X00F1: value of the event counter of input TOR2
•
Byte 6 and 7=0x0001: current state of output TOR3 (because it is configured as an output in this example)
•
Byte 8 and 9=0x0000: input disabled in this example
•
Byte 10=1001 1100 (0x9C): which gives:
• <0> TOR1: Current state = 0
• <1> TOR1: State at the sending of the previous frame = 0
• <2> TOR2: Current state = 1
• <3> TOR2: State at the sending of the previous frame = 1
• <4> TOR3: Current state = 1
• <5> TOR3: State at the sending of the previous frame = 0
• <6> TOR4: Current state = 0
• <7> TOR4: State at the sending of the previous frame = 1
