Good day to all~
I'm new to the world of plc and programming hope u guys could assists. thanx.
I'm using STEP-Micro/WIN V4.0.8.06 with modbus library installed to program S7-200 CPU226.
my question is how do u mapped the input or output to the modbus address?
i've read all the manual and help file on how to use the modbus library instruction but cant really understand it.
i know that 10001-10128 are discrete inputs mapped to I0.0-I15.7
are they mapped by default?
can i mapped I0.0 to 10021 instead of 10001?
if i program I0.0 to set output coil V0.0 to 1, then how can i map V0.0 to modbus address 100021 for example?
i know this all are like silly question for u guys.. but can anyone help me with it? Thank you so much for your time and consideration.
Thanks and regards,
Amru
