Hello people, I have established communication between a S7-200 and a S7-300 via profibus DP using an EM277 module. The network is well configured and i´m using a 32 Bytes Out / 32 Bytes In configuration on the module. I am able to send the bytes i need, but i also need to send one Double Word variable. How can i do that ? Suggestions? Thanks in advance, Boardwalk
Boardwalk posted a topic in HMI & SCADAHi people, I'm kind of a newbie with this things and i'm looking for some hints. All the help is welcome. I have a Magelis HMISTU855 and i'm trying to connect it to a S7-200 PLC via a XBT ZG929 MPI-Bus adapter. To do that i have a stripped RJ45 cable to whom i need know how to make the wire connection in a D9 connector, in order to match the pinout of the MPI-Bus adapter. How should i connect the wires from the RJ45 cable to the D9 connector? PS: the RJ45 is plugged into the COM1 port of the Magelis Thank you in advance, Boardwalk.
