Hi there, I'm seeking advice on connecting a Lika SMA5 absolute measurement encoder directly to an S7 1214C PLC. The encoder produces an SSI signal. If you have any knowledge or experience with this setup, please share your insights. Your input would be greatly valued.
To interface with a profinet network, you can opt for a Siemens TM POS input module or a compatible third-party module.
The signal board SB1221 is compatible with encoders up to 200 kHz, specifically designed for quadrature input. Please note that the encoder requires an SSI interface for proper functioning.
In order to connect devices on a Profinet network, you can use a Siemens TM POS input module or a third-party option. Have you considered the 6ES7138-6BA01-2BA0 module for this purpose? How will you integrate this lineup with an absolute encoder? Thank you for your assistance.
Can you provide an update on your progress thus far?
I own a PLC S7 1214C and am considering purchasing an IM 155-6 PN BA to connect a TM PosInput 1. We are currently exploring programming options for the TM PosInput 1 - are there any pre-existing FC/FB available, or will I need to create my own program from scratch?
Sure, the S7 1214C has integrated input channels for high-speed counters, but it doesn't inherently support SSI protocol. A solution to this could be using an additional communication module that can convert your SSI signals to Profinet, which the S7 can readily accept. Companies like Pepperl+Fuchs produce these kinds of modules, specifically the gateways of the ICE family. If you're working with Lika encoders, the DRS01700 could also be a viable option, as it features integrated SSI inputs. Once the signal is converted, you just need to configure the gateway and PLC to communicate with each other properly. I would also recommend reaching out to technical support for step-by-step guidance to avoid any configuration errors.
Hey there, I've worked with a similar setup before. One thing to remember when connecting any absolute encoder like the Lika SMA5 to the S7 1214C PLC is ensuring the compatibility of the SSI signal. This might involve using a signal converter to communicate between the encoder and the PLC. Alternatively, you could explore some expansion modules for your PLC as they might have integrated SSI inputs which can make the process a lot smoother. Once everything is physically connected, you need to program your PLC accordingly to interpret the readings from the encoder. Keep an eye out on your Lika's documentation for specific wiring diagrams and SSI communication routines that can aid this process.
Hey! I’ve worked with SSI encoders and the Siemens S7 series before, and connecting a Lika SMA5 should be pretty straightforward. You'll need an SSI master-capable module, like the optional 6ES7 972-0BB52-0XA0 card for the S7-1200. Make sure to configure the encoder's parameters in the TIA Portal, particularly the data format and the clock rate for communication. It might take a bit of fine-tuning to get the timing right, but once you’ve got it set up, you should see smooth position readings. Let me know if you hit any specific roadblocks!
Hey! I’ve worked with SSI encoders and S7 PLCs before, so I can share a few tips. Since the SMA5 outputs SSI, you’ll need a dedicated SSI interface module on your S7-1214C, as this PLC doesn’t support SSI directly on its onboard inputs. Look into Siemens’ S7-1200 SSI interface modules, which can handle the serial data from the encoder. Also, make sure to configure the encoder settings in your TIA Portal project correctly—like cycle time and resolution—to ensure accurate readings. Good luck with your setup!

Answer: Answer: To connect the Lika SMA5 encoder with an S7 1214C PLC using the SSI signal, you would typically need to configure the PLC to receive and interpret the SSI data transmitted by the encoder. This may involve setting up the communication parameters, such as baud rate and data format, to ensure proper data exchange between the encoder and the PLC.
Answer: Answer: When connecting the encoder with the PLC, it is important to ensure compatibility in terms of communication protocols and signal types. Additionally, you may need to configure the PLC software to interpret the SSI signal correctly and map the received data to the desired parameters within the PLC program.
Answer: Answer: Yes, you may need to write a PLC program that includes instructions for reading and processing the SSI data transmitted by the encoder. This programming would involve setting up the necessary communication blocks, data structures, and logic to handle the encoder data and integrate it into your control system.
