In one our plant we do have few S7 200 SMART plc’s. Is it possible to use any of the available Ignition device drivers for communicating with this PLC. ---

Any update on this ? Because we have multiple S7200 SMART PLCs and we want to connect it with Ignition. ---

We don't have one of these to test with, but you could try just using the S7-300 driver. It looks like these S7-200 "Smart" PLCs are a new/different product than the legacy S7-200 hardware. ---

Any updates on this? Not sure if this is what @chen_zhe is suggesting, but does using the S7-1200 driver for a S7-200 SMART work? Thanks ---

Dear all, Any updates on this topic? As chen\_zhe mentioned, does S7-1200 driver for S7-200 SMART PLC work for reading the PLC read register addresses, such as I0.0 (input register), Q0.0 (output register), V100.0 (variable memory), etc? We could read limited variables from S7-200 PLC using ignition S7-300 driver, but we need to read all the variables. Or there is another method that using gateway to convert the protocol to OPC UA? Thanks! ---

Hi, I just tested and update that the s7-300 driver worked ok with s7-200 smart. Here is some picture. ![IMG_6884](https://us1.discourse-cdn.com/inductiveautomation/optimized/3X/9/7/977c8299d69d1e27c35a062539e73c23fd7937a4_2_690x35.jpeg) ![IMG_6883](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/c/8c883fc53be8482a59732607fe75ffe79bccd888.jpeg) ![IMG_6880](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/7/57f719ab3abc2a0e34e4bafbf9d584012f729e09.jpeg)
