MODBUS/TCP Fieldbus manual
The device supports two manufacturer specifi c function codes for confi
guring:
� I/O points 1 - 4
� I/O point 7 - 8 (Clock I/O)
� Clock Ratio
� Analog input
� Capture input/trip output
� Trip on relative position
� Upgrading fi rmware
These are:
� 65 (0x41) – Read specifi c functions
� 66 (0x42) – Write specifi c functions
4.3.1 Manufacturer specifi c commands using 65 (0x41) and 66 (0x42)
General purpose I/O setup The ASCII of the command mnemonic is sent in revers order in the request PDU i.e.
1S, 2S etc. The parameter string is written or read in normal sequence.
MCode mnemonic S1 (I/O 1) S2 (I/O 2) S3 (I/O 3) S4 (I/O 4)
