  1. I think I got it. I hope this helps someone else. Out of curiosity I replaced the existing CC-Link card with a new card with default parameters. The default parameters did not change. This means the CC-Link card had the parameters saved in EEPROM and was sending the parameters to the buffer memory of the CPU. For whatever reason, the original programmer did not leave the logic in the code to update the EEPROM with changes. I put the old CC-Link card back in, looked at the buffer memory values, and wrote down the parameters that needed to be changed. I reinstalled the new CC-Link card and followed the parameter setting example in the manual. The only difference is that I only wrote the specific parameters that needed to be changed. The I/O had to be set up too.
  2. I am adding a remote device to an existing cc-link network. The master station is an A1SJ61BT11 and the CPU is A2USHCPU-S1. The CC-Link network currently has 20 remote I/O stations and I am adding a remote device. The A1SJ61BT11 has parameters written to its internal memory. In order to add my new remote device, I think I need to only change two parameters: First, I need to change parameter address H1 from 20 to 21 since my device will be the 21st. Second, I need to change station information parameter address H34 from 277 to 4373 to enter it as remote device. I looked at the example in IB(NA)-66721-J(0310)MEE, section 6.3. In the example, they are setting up the parameters for the first time. However, I am only changing two of the parameters. I followed the example except I only entered rungs to change the parameters for H1 and H34. My question: If I run the parameter setting program to only enter parameters for H1 and H34, will it affect the other parameters the original programmer entered? Could they go back to default? Any advice? Thanks in advance
  3. Combine 2 Machines with CC-Link

    I would like to combine two existing machines with CC-Link. Each machine has a QJ61BT11N set up as its Master Station. The larger machine has 26 remote I/O and 4 remote devices. The smaller machine has 1 remote device (see the attachment). Each are already programmed and running. The larger machine has HMIs that I would like add screens to in order to control the smaller machine as well. The smaller machine would basically just need to send and receive a handful of signals... start, stop, manual, origin, e-stop, fire specific outputs, etc. What would be the best way(s) or simplest way(s) to connect and communicate between these machines? I am open to any advice and ideas. Thank you Machine_Addition_Via_CCLINK.bmp
