5) Status_XY
a) There are two Statuses provided, one for each protocol. This gives access to the overall status of
that Protocol. Each Bit has its own meaning as follows:
Common Status: 0x000000FF (bit 0-7)1 st byte
Hex: Bit Position: Decimal: Explanation:
0x00 0
0 if we are a Slave/Server
0x01 0 1 if we are a Master/Client
0x02 1 2 connected (0 not connected)
0x04 2 4 first time scan
0x08 3 8 idle (usually added to connected)
0x10 4 16 running (usually added to connected)
0x20 5 32 bit not used
0x40 6 64 recoverable fault
0x80 7 128 nonrecoverable fault
For this example, the ETC Status is mapped to a PLC tag called PLC_Status
Example: ETC Status is 0x00000013 (19 decimal), here is the break down
Hex Bit Decimal Explanation
0x01 0(on) 1 if we are a Master/Client
0x02 1(on) 2 connected (0 not connected)
0x10 4(on) 16 running (usually added to connected)
Total: 0x13 19
External Faults: 0x0000FF00 (bit 8-15)2 nd byte
Hex: Bit Position: Decimal: Explanation:
0x00 8 0 local control
0x01 8 256 remotely idle
0x02 9 512 remotely faulted
0x04 10 1,024 idle due to dependency
0x08 11 2,048 faulted due to dependency
Recoverable Faults: 0x00FF0000 (bit 16-23)3 rd byte
Hex: Bit Position: Decimal: Explanation:
0x01 16 65,536 recoverable fault - timed out
0x02 17 131,072 recoverable fault - Slave err
