Hi,

I'm sure you have seen the manuals:

Control Module (CM) Technology - Efficient Engineering with SIMATIC PCS 7

SIMATIC PCS 7 Process Control System Compendium Part C - Equipment Phases with SFC Types (V9.1)

But in short:

Control Module Types are created in the master library. It's a CFC chart with blocks that function together to create a functionality. Like a simple valve: The CFC chart contains a VlvL, two driver input blocks for the feedback signals and an output driver block to open the valve. Furthermore you can include three Interlock blocks to provide Permit/Protection/Interlock functionality. When all blocks are interconnected with each other, you can define in the technological editor what you want to define as technological I/O.

When looking at TIO, you must think of it as follows: The CFC chart with all the blocks is a black box and with TIO you can define connections to and from the black box. These interconnections can be used by a tool called: PAA (Plant Automation Accelerator) where you can do bulk engineering because when the type is created, you can create instances from that type. You may want to define a different monitoring time for valve x and valve y. In this case, you define the monitoring time as TIO and then you are able to define this via PAA. You won't need PAA, because you can create a copy of the type in the PCS7 project just by using copy and paste in Plant View.

What you can also do in the TIO is define variants. It is possible that valve x you only have a feedback open signal and no feedback close, but valve y has both. You can then define that the driver block FbkOpen is an optional block. When the instance is created, you can define the correct variant. This way, you only have to built the type only once. 

A big advantage of CMT (over the old PTT (Process Tag Types) is that you can synchronize. If you add an block to the type, after synchronizing all instances have the same block. 

The same applies basically for the EMT and EPHT. The only big difference is that for the EMT/EPHT a SFC type component always exists inside the CFC. The synchronization is the same.

The difference between EMT/EPHT is that with a EPHT, you can control EMT, so Equipment Phase can control one or more Equipment Modules.

Hi,

Can someone provide me video tutorial on how control module, equipment module and phase works.
I have tried the official manual provided by SIEMENS but have difficulty understanding it.

Thanks, and Regards

 Hello Adithyan,

Thank you for reaching out with your query. I understand that the official SIEMENS manual can be quite dense and sometimes difficult to follow. While it's true that most people rely on manuals, there are indeed some helpful video tutorials available online that can provide a more visual and practical understanding of control modules, equipment modules, and phases.

Here are a few video resources that might help:

CMTs

Additionally, you can refer to the official SIEMENS support page for more detailed documentation and application examples:
