    That worked!!!! Thanks for the help. I was treating each register location in the table, as a 16-bit byte, not an individual bit. Changing the start Byte to multiples of 16bits worked great.

    Will give it a try.

    I contacted Advantech and they were not able to help me other than to point me to where I could find the register table. I did do that but was not successful in making it work. I posted another question on this forum that includes the table and the program I wrote to make it work.

  5. David T. started following DASYlab Modbus and Advantech Adam Modules and DASYlab Modbus and ADAM-4150 Digital I/O. Inputs work, outputs don't.

    I have a simple DASYlab 12 Program that I can not activate any outputs on an ADAM-4150 Digital I/O module. The digital inputs work fine. I have Channel 0 set up as a counter. To set up CH0 as a counter I used the Advantech utility program. However, I am not able to clear the counter. I am also not able to activate Digital Output 0. I have tried both Digital and Analog outputs for the module. The status displays correctly but it does not function on the Digital I/O module. Register 00017 is Digital Output 0 Register 00033 is Counter Mode CH0 - (Start=1, Stop = 0) Register 00034 is Clear Counter CH0 - (Clear = 1) How do I make digital output 0 work? How do I clear the digital input 0 counter? ADAM-4150 Modbus Mapping.docx DASYlab_ADAM-4150_Test.DSB

    Hello, I am working on an application that monitors a tipping bucket rain gauge. I have four modules on a Modus/RS-485 network. Three analog input modules (ADAM-4119) and one 15ch digital I/0 Module (ADAM-4150). The time it takes for the digital input, DI0, to be read is ~550mS. In this time the tipping of the bucket can be missed. The ADAM-4150 has a very nice latch function that would be perfect. I could read the input and then clear it if it reads high. The ADAM Utility program works great capturing tips and then manually clearing them. My problem is I don't know how to clear the latched input using Modbus. Can anyone provide help on how to clear a latched input with Modbus? I would attach my current DASYlab worksheet but I don't have a place with a URL to host the image. Thanks for reading my post!
