Hello, I’m having a problem with a IRB4400 2000 s4c+ controller. It is been for years now that modules are added to a existing program. Last time after changing a program (adding a module) by a network connection, and then loading the program into the active memory, I got this message: MCO:PGMLNK.C 3451 20311 Enable Open 10014 System error Status I had to cut off the power, so he has done a P start, en had to do a restore of the previous backup. I thought that we were running out of const robtargets, so I deleted the ones that were not used. After trying again, it worked, but when you reload it once more, I get this error again. Can somebody help me with this problem. Best regards, Q ---

Please add a Backup so i can see your configuration … (add Log file) Enable 1 open, can bee open by a lot of reson. “Panel board” and the “conector board” are runing a internal can bus, from the I/O-computer. I think “Enable 1” is runing through all these components.. Check electrical drawings can give a hint! Check errors on console port .. (9600 boud) givs a hint on which part is failing in start upp mode.. (if you have lookt at the print out before) I think you can se status on “sys inputs” by typing EIO\_show or eio\_show in the terminal. A hint about “show” comand in a terminal window write → lkup “show” and a list on show instruction will appear I forgot the KERNEL - C-code can also be a resson or a very hevy load on the I/O-buss if Poll rate is to low. ---

Hello… When did the error occur? Upgrade? runing program ? Reboting,restart ? Loading a backup? or configuration of multitasking? event\_rutins? Will a i Start help ? a I-start will reboot a system to default configuration. (Program and motor-configuration I/O-configuration) will be reset to default… go to 1. service , 2. restart 3. then press 1,4,7 and I-start will be present! If you still have problem after i-start, then it can be the robotware “c-code” fore the robot.. If system ok … load a working backup else.. try to do a C-start 1. service , 2. restart 3. then press 1,3,4,6,7,9 C-start C-start will empty the robotware and the “system” include “system/Backup” folder copy backup from folder to PC by FTP. to save rapid code and configuration… for loading later! Now you have to load a complete new “system” from “RobInstall” systembuilder for s4c+… If NOK now then it is a hardware problem… ---
