Back in 2010 (or was it 2011?) I was really wanting to have a simulation mode on Vision PLCs. Because it would help to test an application without having the PLC. Since that wasn't possible, I proposed an idea that Unitronics rents time slots to actual PLCs connected via Internet. That way programmers would be able to test their code on actual hardware. I know, I know, PLCs are supposed to be serious business, and it's often mentioned that you can buy: 1 x V120, 1 x V430, 1 x V700, and 1 x V1080 for the price of a Siemens software license and a set of genuine programming cables. Here's my rebuttal: a local company, due to Covid-19, has implemented a testing-as-a-service with their hardware dev kits. They call it Planet Debug. Every dev board is connected to Internet (through a firewall) and has a camera pointing to it. You choose your hardware, how big a time slot you need, and you get to test your code on real hardware. Now imagine a wall covered with Unitronics PLCs, each with a dedicated VPN tunnel to an end user, billed by hour. Let's begin at $10/hour. Unitronics staff could charge a "configuration fee" for connecting I/O modules to the PLC, or some specific elements such as stepper motors, weighing scales, heaters, temperature probes, etc. User would be able to download HMI and ladder code, and check out how it actually looks and operates. A web camera would be recording the PLC screen and I/O module LEDs, so design could be fully verified.
Hello: I ve been working in an application in which I need to show some HOURMETERS from working motors. My application is been developed in a V1210 unit, and I am using VISILOGIC version 9.8.31 As I see, it is supposed to be easy. Whle the starting motor order is held ON, the hourmeter should count up time. I want to show the numbers as the image attached. This is, the counter will count up to 99999,9 until RESET to 0000 So my prupose to do this in the network image attached, Well, I also used the VIRTUAL PLC tool to test it, but it seems not to work. In the simulation I can see the 1 second pulses, but the counter does not increment (or at least is not showing it). So, can some tell me what I am doing wrong? or the problem is the simulator? Hope you can help, Joaquin
