AutomationDirect Nitra PAL or Pneumatic Automation Link is a highly versatile and scalable field I/O and pneumatic system integrated via Ethernet IP. The Nitra PAL is easy to integrate with any PLC via Ethernet IP. We’ve made it simple to integrate with your Do-more Family PLC by creating an example program. Just keep in mind that the Ethernet port used must be the built-in port of the CPU or the BX-P-ECOMEX. H2-ECOM100 and BX-P-ECOMLT do not support EtherNet/IP scanner functions. Please follow this link or scan this QR code to get all the software and documentation for your system including the example program. This video assumes that the PAL system has already been configured. If you have not already configured it, please see the video in the link above. Looking at this example program the main program sets the IP address of the PAL and the communications interval and runs the other programs. PAL has a great failsafe system which will not allow an Ethernet IP message to write to the outputs if there is not a connection. But, since Do-more uses unconnected messages, you have to tell the PAL to accept writes by writing a 1 to attribute 3 of assembly instance 104. The program has set this up to occur any time the messaging is enabled here in the enable writes the program. There is a program to map input data and one to map output data. These are great in that all the data is arranged in appropriate data types with simple logical nicknames. This last program is where the reads and writes actually take place. Let's look at the data. SL0 lets us know if the PAL is accepting writes and the first byte of V0 is diagnostic data from the PAL. The diagnostic codes are listed in the PAL manual. Right now I have the PAL powered down just to show the effects on SL0. Once powered and communications are re-enabled we see the PAL is ready for writes. Now we’ll look at an input which is mapped to V25 and we can see the input toggle and I’ll cycle a valve. The easiest way to see where all the data is mapped is the Documentation editor. Here we see the valves, then we can see the I/O modules. So that’s it. We’re up and running with our PAL connected to our Do-more PLC.
