Siemens S7-1200 RS232 serial communication using the CM1241 module with the SEND_PTP Function Block

I looked around the internet a lot trying to find info on how to set this up and there is almost no information out there. Most Siemens equipment doesn't use serial communication, but I was in the unique position of having to send Hex data over RS232 serial from a S7-1200 to a servo motor controller.

I figured since there's almost nothing online to help anyone with this task, I'd make a video about how to do it for my students and anyone else that happens to be in a similar situation now or in the future.

This example uses the older model CM1241 that only has firmware revision 1.0. All of the examples I could find that were remotely helpful were using the newer model of the CM 1241 with the 2.0 or higher firmware. I even found some places saying that the older hardware with the 1.0 firmware that I have could not use the SEND_PTP function. Obviously this is not true.
