Engineer Posts: 4 Rating: (0)	Hi, I have used a CP341 modulewith its 2 FBs P_RCV_RK and P_SND_RK for Modbus comms. I now am using a CP441 module, reading the manual however it says you need to use the BSEND and BRCV SFB blocks. As Ihave alreadydeveloped a FB for the CP341 I was wondering, can the P_RCV_RK and P_SND_RK FB FBs be used with the CP441? Also are there any example projects available illustrating how to use the CP441 SFBs for Modbus comms. Any help would be much appreciated

You als must have the Modbus software ptp, including a dongle. When you install the software, there is also an example installed in Step7. Open project and look in tab Sample projects. Here you can download PtP software Modbus master: http://support.automation.siemens.com/WW/view/en/8713784 And here if you want to use Modbus Slave: http://support.automation.siemens.com/WW/view/en/8715908 Hope this will help. Best regards, Wizard
