Dear RugbyGuy, May i know how to configure the I/O of CM1242-5 in hardware configuration? For the CPU1214C, i have 14DI, 10DO and 2AI. For the extension slot, i have one unit of SM1221 and SM1222 , 8DI and 8DO. I would like to get the communication for the CPU to get all the data from the modules to be mapped to my main S7410-5H PLC. Or anyone else know the ways? Appreaciate so much for helping. ------------------------------------------------------------------------------------------ AttachmentS7-1200 HardwareConfig.zip (418 Downloads) |

Thanks 51N3P for the replied. Here attached with some pictures, i think there are two release ways to establish the CPU communication from S7-400 (master) to S7-1200 (Slave). One is by load/transfer commands, DPRD_DAT, DPWR_DAT ; the next one is by PUT, GET. In my plant, their architecture is by using profibus. The only ethernet port was used to connect the siemens touch screen HMI. Now left with a CM1242-5. By using PDM, i can detect the CM1242-5 is in the profibus loop under the Y-link, but no matter how i configured the CM1242-5 GSD I/O, i could not get the communication established. It showed "Module not available" . Appreaciate much for helping~ AttachmentS7400-S71200 Communication.zip (478 Downloads) |

Okay, I do not know why it is showing "Module not available" but have a look at the following FAQ: https://support.industry.siemens.com/cs/ww/en/view/109744337 Basically it should work in the same way with an S7-1200 and there should not be a difference in the configuration steps. |

The configuration for CM1242-5 via Profibus Slave is quite easy. Here attached with some guidelines. There are two important things to take note, 1. the input of S71200 is the output of the S7400. Vice versa. 2. the number of word/byte must be the same configuration as the S71200. Thank you. AttachmentCM1242-5 Configuration.zip (409 Downloads) |
