Read page 24 of this - you'll need to "borrow" the float license to the laptop while on network and then goto site/ https://www.femto.eu/wp-content/uploads/2017/11/SPLMLicensing_user_guide.pdf

Aging eyes and small monitors.  Step / Stop looked much the same. I was trying to find the parameters which contained the Status Information about if it actually enabled and if any stop signals are present.

Might I suggest that while trying to run the drive that will not run you check the following: B006 - Drive Status B013 - Control In Status D391 - Stop Logic Status  

Best Practice suggestion - Never leave a force active in a system and disconnect your programming terminal.  Write code to repalce the force if it needs to remain.

another option - Radwell International

your picture looks like you're setting the force value , if so did you enable i/o forcing?

 If you're running Windows10 Professional or Enterprise you should have Hyper-V VM Manager by default.  It will run the RSLogix but be a hassle doing plc conconnection thru USB or serial.  For usb and serial I'd reccommend VMWare.

Welcome to mrplc.com. I believe that you will find that asabtcp.ocx comes from Automated Solutions - https://www.automatedsolutions.com/products/activex/asabtcp.asp and you will need to purchase the license for it from them. It has been some years since I used the AS ocx, but I will warn you that when I was using it you needed to be careful transferring arrays. By this I mean that when we used it back 20 years ago , the Rockwell OCX loaded element 0 thru element N while the Automated Solutions OCX loaded element N through element 0. We had defined element N being "FFFF" as a trigger to process data , so when we switched to Automated solutions our code started processing data while it was still loading. Quite a mess until we sorted out what was happening. 

PLC 5/40 and serial comms and only 250 ms between read calls. I'd try a 60,000 values in the thread.sleep command and see if things behave differently. {One read per minute to start and if that works drop down. } Just a quick off the cuff first idea!

Communication as I understand it goes PLC to HMI to WEBPAGE. IF that assumption is correct, then I would ask is the animation color of the object at the HMI Screen changing in sync with the PLC . In other words, are we looking at a PLC to HMI comms delay or issue or an HMI to Webpage issue?

IT is old school and time consuming to code, but if you are input limited, but do have 4 inputs and some spare outputs you can diode isolate the same output of each switch and use one input for all 1st output of all switches.  you then poser one switch at a time and after powering the switch read the inputs it generates and then move to the next switch.  Had to do this once on an old omron system that only had 5 spare inputs left but an entire 16 bit bak of outputs spare.

So I am posting back after finding the correct answers. Servers 1, 2 & 3 are setup under RDLicensing to use Server 3 as Per Device Licensing. Server 4 is setup under RDLicensing to use itself as Per User Licebsing. I then split the cals as 25 per device , 25 per user,

I have an Aveva System Platform 2020 System using thin clients and RDS Services. Server 1 - OI/HMI Server - supports 10 Thin Clients and one console session Server 2 - OI/HMI Server - supports 10 Thin Clients and one console session Server 3 - Development Server - Supports 1 Thin Client Development Session or RDP Development Sessions This all worked great during startup testing while RDS was in its 120 Day Grace period. My IT Depart has stood up Server 4 which has RDS Cals for 50 users. Now the question no one can seem to answer - What is the procedure to setup RDS Licensing so that Servers 1,2 & 3 draw their licenses from Server 4. Mr. Google shows tons of possible videos , but none seems to be a direct answer. Anyone with IT RDS experience that can shed some light?

I've had positive results with CLGX/DHRIO ; Prosoft and RedLion converters.  Of course comparing DH+ to Eth/IP is like comparing a tortise to a hare. for red lion check out - https://www.redlion.net/family/protocol-converters

I concur with @pturmel that option 2 is the best approach.   I would however be sure and run your connection count calculations for the I/O to the processor. There is a slim chance that you might want multiple ethernet cards in the Host Rack. I'm thinking one card for Programming and Scada Access, one card for five stations and another card for five stations. You'll also want to consider using Ethernet Ring with all its bells and whistles for maximum uptime. You also might consider two CPU in the Host Rack and configure for redundancy.  Obviously the cost goes up, but so does the stability.
