Slow editing/assembling rungs on CJ2 CPU33

7 posts in this topic

Hi,

On my ongoing project I'm facing slow editing/assembling of rungs when ever I have to make changes online. It was OK earlier, but when the program steps have increased, I face this issue. I used to write a lot of comments on instructions, rung comment etc. Not sure that's the cause, but I doubt so.

It's CJ2M CPU 33. I'm connecting using USB. The I/O table consists of a CJ1W-ETN, with 3xID262, 1xOD262. The Ethernet IP had around 34 devices, [Remote I/O, servo & SMC valve banks]. The line also had 4 Proface HMI on Ethernet.. Attached is my memory view.

Googled about it, unable to find any clue. Does anyone come across, how to fix this.

My CX-Programmer version is 9.8

Thank You

Im using a cj3m_32 it can only run 10k of lines, the 33 can run 20k . Taking in consideration you have 14k of lines it is normal cycle time. Did you ad something new program or hardware to the system or network?

Question Have you tryed to acces the CPU via the UTP poort/ ip adress? usually a USB is just a serial poort  and they are very slow so this could be the bottle neck you experiancing
