I am currently researching five different PLCs and consolidating their data into a CompactLogix 5380 for easier data manipulation. I am facing challenges with configuring the message block in the CompactLogix to interface with a MicroLogix 1400, as I keep encountering a Parameter error in the module configuration. The message block is set up as a SLC Typed Read, with the source element specified as N201:0 and the number of elements as 1, with the destination as an INT data type. Configuring communication with other SLCs on the AB-X2-ABDHP is also proving to be a daunting task. Has anyone else encountered similar issues when attempting to do this?
Are you viewing RSLinx or the I/O tree of the CompactLogix? It seems like you are connected to the CompactLogix via USB and exploring the network. Make sure the MicroLogix is not included in the I/O tree as this could disrupt communication, as it is unable to establish an I/O connection and may become confused by repeated connection attempts. Can you provide the specific error message from your MSG instruction?
The screenshot displays the Linx connections from a USB connection. There are no devices listed in the I/O configuration tree on the PLC. I am experiencing a parameter error message in the module configuration with the MicroLogix.
If you're unsure about setting up communications for the other SLCs on the AB-X2-ABDHP, you're not alone. Which type of SLC is connected to the AB-X2-ABDHP, and which port is it using? When it comes to sending MSG instructions to controllers on DH+, they are actually directed through the CIP path to the DHRIO module for processing on DH+. Check out the MSG Help for guidance on configuring the message to reach the DHRIO, where you can specify the port and node for message execution.

To communicate with SLCs using the DHRIO module, check out this discussion thread for a comparable case: http://www.plctalk.net/qanda/showthread.php?t=112454. This instance involves a ControlLogix configuration, connecting through an Ethernet module instead of the built-in Ethernet port on the CompactLogix. Keep in mind that while similar, it may not be an exact match.
It looks like you're having some trouble with your PLC configuration, which can definitely be a bit tricky. From what I understand, you're trying to read a single integer from the N201:0 location in the MicroLogix 1400 using a SLC Typed Read message. It may be worth ensuring that the data type matches on both the source and destination side - you mentioned that your destination is an INT data type - maybe verify that the source data type in MicroLogix 1400 PLC is the same. For the AB-X2-ABDHP, can you provide more details on the specific issue you're encountering? Are you receiving any error messages? Remember, communication setups can be complex, but each hurdle you overcome builds your technical expertise in this field.
I have experienced similar issues in the past. The issue may be arising from trying to read an array element of a MicroLogix PLC as a single element from a CompactLogix. Try reading the MicroLogix data as a block transfer where you read the entire array in one go instead. Ensure that you have correctly configured the MicroLogix PLC's message block to match with the CompactLogix's setup. For configuring communication with other SLCs, you could leverage advanced interface modules or suitable bridges that can convert the communication for you. Consulting the manufacturer's communication guides can be very helpful in this instance. Keep persevering, debugging these issues can sometimes be challenging, but usually have logical solutions.
I've had a similar issue before and what helped me was to check my file types closely as the MicroLogix treats integer files and input files differently. If your N201:0 source element is in fact in the integer file, remember to match it with the equivalent register in the CompactLogix which also utilizes the integer data type, not input. Also, make sure that your source and destination elements are compatible in terms of data type. For the AB-X2-ABDHP, you might need to update your firmware or double-check the network settings. Sometimes a minor adjustment in these areas can swiftly solve a major problem.

Answer: Answer: To resolve a Parameter error, ensure that the configuration settings in the message block match the requirements of the MicroLogix 1400. Verify the source element, number of elements, data types, and communication settings.
Answer: Answer: Communication errors may occur due to mismatched configuration settings, incorrect addressing, incompatible data types, or network issues. Double-check the configuration parameters and ensure they align with the requirements of the SLC PLCs on the AB-X2-ABDHP network.
Answer: Answer: Common challenges when consolidating data include configuring message blocks correctly, addressing inconsistencies, dealing with communication protocol differences, and troubleshooting parameter errors. It's essential to thoroughly understand the communication requirements of each PLC and ensure compatibility with the CompactLogix 5380.
