may be beneficial to know if a Server/Slave device is down. By using this Network
Bitmap Status you can expose the connection statuses of individual devices.
b. 0x00000002 shows that only device 2 is connected
c. 0x00000003 shows that only devices 1 and 2 are connected
d. 0x00000004 shows that only device 3 is connected
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

Total: 0x13 19
External Faults: 0x0000FF00 (bit 8-15)2

Hex: Bit Position: Decimal: Explanation:
