Dear Experts, I have a scenario that using S7-1200 as Modbus Master to check number of Modbus Slaves and which of it is alive, so that the Master knows what to do/message with other Slaves.
During an online search, found the Library for Modbus RTU (LMRTU) https://support.industry.siemens.com/cs/us/en/view/109747565 In the documentation, it only mentioned CM1241, and this library still in the era of TIA V14, I think that should be still valid. Is that also possible to use Library for Modbus RTU (LMRTU) with CB1241? I am using TIA V17. Currently I don't have multiple CPU to test with because this is before the purchase, now deciding to whether use CB1241 or CM1241. Thanks!! nicki |
