I figured it out. Just wanted to update this thread.

I have a question. If the PC sends me a command in ASCII such as: #AB,ALIVE,LR When received into the buffer it will be in HEX correct? I can then parse the data to extract the word ALIVE and IF it equals ALIVE then I can trigger an output in my FB to send a response back that says ALIVE. Is that right? Or do I need to convert it then parse it?

Michael we are located in San Jose California. I've been on site doing startup and testing on the system for the past week. Our customer is fortunately in the same city.  They declined downloading Kepware to their PC in the wafer tool. Bummer. So I am now having to write the necessary strings in STL in CX Programmer. I've been reading the manuals and planned to use FB's for the opening and closing of the socket. This is all new to me and now I have to be done by this Sunday. Sure.

This is the document with the communications protocol the client has provided to us. QORVO Chemical Mixer - Protocol - ASCII Command - v2.docx

I'll have to ask the client. However, it is just a computer running windows with their custom software.  

Gents, I'm up against a wall and reaching out to find a system integrator that can assist us in writing some code for our PLC program. CJ2M-CPU11 communicating with an NS8. The ETN21 is supposed to receive and send info in ASCII to a computer. We have never setup this type of connection. The project is due in two days and I am out of time to figure it out on my own. I wanted to know if there is anyone that we can hire to write this code for us. I've read through all the manuals on TCP connections, sockets, and the like. I have more questions than answers at this point. The logic in the program is written. I just need the ASCII code and communications written. I understand that the ascii will come in and go out as HEX. What I don't understand is in the instruction manual W421 section 6-7 page 129 there is a programming example to open a socket in TCP. Do I just copy and paste this code? Where do I put the SEND RECV commands? Where do I put my multiple DM addresses (BSET) to write the ascii words (hex) to be sent? Its all very confusing for me. Desperately need help. I could figure it out over time through experimentation. However my boss has stated I am out of time and this unit ships in two days time. Any help or suggestions on whom can assist in writing the code that's adept at this type of thing is greatly appreciated.

I just spoke with Omron tech support. System memory allocation is not critical for my setup. I am not utilizing any of the status bits or words in my PLC program. The error I'm experiencing points to communications issue. The tech stated the node addresses should be the same but he didn't sound certain. I currently have them both set to 1. I will try making them different and the same. I've also been told its ideal to set them to 0. Well, the PLC was set at 1 when the software was initially developed by other parties. Beyond serial config settings it could be my cable I had made. I'll be checking it and may end up making a new one myself.  

Thought I had this all figured out. Went on site and connected the panel to the PLC. Downloaded the software and I get two errors on the touchscreen. Timeout error for system memory allocation. Timeout error for downloading HOST1 data. I'm at a loss. I don't completely understand what I am supposed to put in the fields for system memory allocation under setup. Can someone point me in the right direction? I'm under the gun to get this done like yesterday. Another question. If I am using full duplex DF1 serial comm does the node number in the panel need to match the station number in the PLC? 9621_SCR_V2.IPP

Ok, thanks!

Thank you for this! Very much appreciated. As I am not yet proficient in RSLogix 5000.... do I need to insert a JSR instruction in the Main Routine to execute my IO Mapping Routine? Or will it scan all routines? I didn't originally write this program. Just got stuck upgrading it and learning as I go. I am much better with RSLogix 500. Enjoying learning this software as well!

Quick question: I found under the Logic drop down menu an option to Map PLC/SLC Messages. I created an N7 array and placed it in the table. Is this necessary? I have created my N7 array in the edit tags table so not sure if I also need to have the above done as well. I am aliasing single bits of the integer word to my tags that are used in the HMI. Then inputting the N7 addresses in the HMI symbol table. Courtesy of Automation Direct https://www.automationdirect.com/microsites/c-more/software-help/Content/323.htm

Thank you Jay!

Attached is the Omron document on how to setup the serial port for AB. Is that what you're looking for? Edit: Jay beat me to it. Duplicate file. Omron NS Series Connection to AB PLC.pdf

Thank you Joe. This is very helpful and yes, it all makes sense.  I didn't understand what the file number was or where to find it. Sorry for the late reply. Was on a job in New York all weekend. I would happily use C-More or Red Lion. I didn't realize it would take mapping all my HMI tags in the PLC. We use Omron almost exclusively in all of our systems we build. Anthony

PLC: 1769-L32C Input Cards: 2 Each 1769IQ16 Output cards: 1 Each 1769-QB16 This system has been in operation for 10 years. The client decided to have our company change out the old Panel View HMI for an Omron NS5 communicating via serial. The problem I'm having is the tag names in the Omron touch screen. I cannot use the actual alphanumeric tag name as shown in the PLC in the Omron NS5. When I do it gives me an error message of "unused symbols in project" and I cant download. Turns out I have to use the numeric address. I don't know how to do this. I attached two screen shots. One is symbol input which evidently is incorrect. the other is input direct address which is correct. Problem is I don't know what to put in the "File No." field. In the example provided on the Omron website it is shown as a number. See attached screen shot. Where do I find the file no. for the input or output I am addressing to? I understand slot no. and bit no. of course. Additionally, I can certainly input my physical I/O I am using in the HMI once I know what to put in the File no. field. But how do I assign a numeric address to the internal relays and inputs that are not attached to physical I/O in my PLC program to use in the HMI? Like turning on and off my pump for example. Any help greatly appreciated. I miss the days of using C-More panels. Not as powerful but so easy to work with.
