Is it possible to send fins commands through the cpu serial communications? If yes, let say the read area command. How does it looks like? I have tried every combination I can think of but no response from PLC not even error messages. Im not quite sure if I understand the fins commands and the implementation of it. Do I have send the commands in a specific queue? I'm able to send c commands through the serial port, and I'm getting response from plc. The only difference between c command and Fins command in PLC setting is that I use Host link instant of Toolbus. thank you in advance

I have a control that I want to use a Direct logic 05 plc in. It is a really simple program but it is going into a plant that has a main control panel that runs the plant. I dont know the brand of the plc in the main control. They want to be able to send me a command from their plc to the direct logic to turn on my unit. I suppose that would mean a simple set instruction to my plc. I also have a couple alarm conditions that I want to send them. For example if water pressure is to low I would put my unit in the alarm mode and send them a low water signal. If the chemical is low likewise, I dont have a clue how to do this in my program. Can anyone give me some examples in direct logic plc program for making this happen??? Thank you Thank you Thank you. MikeC

Here is a link to a thread on a recent post showing how to communicate serially to an Omron PLC using VB.Net. This uses the Omron Host Link serial protocols. (C-Mode Commands) It will read 10 DM registers and display them on the form. http://accautomation.ca/implementing-the-omron-host-link-protocol-vb-net/ Here is the source program that can be downloaded.

Hello everyone! Could someone help me and explain me this block of a ladder diagram I'm working with? I do understand the M800 is always ON contact, for the PLC to not lose the values. Also I know that the DIV is a division, the FLT is a integer to floating point (thing I don't understand), the DEMUL is a floating point multiplication (thing I also don't understand), the INT is a floating point to 16-bit integer, and the MOV is for moving a value from a data register to an other data register. Help... :(

Hello everyone! I am not necessarily new to plc's but simply haven't had as much exposure to programming as I would like to have had over the years. I have a project that requires me to cycle three facility air compressors individually so that each one will aquire equal run time (approx) annually. Some requirements are: The start of the next one must overlap for a few minutes before the previous one shuts down, to avoid any loss of air pressure. Also, the system must run all three at once, upon power up, for a short period when the plant is first start up. The run times in this area are not critical either. I have a C200hs Omron PLC and I am using Cx Programmer to write the logic. So far I am using the one minute clock pulse to count down 5 or 6 hours between compressors and using timers to reset them. Does anyone think there is a way to use a shift register SFT to accomplish the same thing easier or? I am open to any suggestions as long as they're not vulgar. Lol. Thanks for any help!
