Hi,
On a modbus block for an S7-314 I need to set the parameter local_tsap_id and have the following description in the manual...
This parameter defines the local port number.
local_tsap_id[1] high byte of the local port number in hexadecimal
local_tsap_id[1] low byte of the local port number in hexadecimal
local_tsap_id[3-16] B#16#00
I understand the port number needs to be 2000. What I don't know is what to put in the high byte, low by fields.
I have my low byte as D0 and high byte as 7 in hex. Does this make sense?
my logic is...
low byte = 1101 0000 = D0 in hex
high byte = 0000 0111 = 7 in hex
Thanks
