I'm having a bit of difficulty with the MSG function on a logix5000. I'm simply trying to get a REAL value ("BH5_Flow") out of another logix5000 and assign it to a tag in the PLC. I've created a MSG function and created a new tag "BH_5_Flow_MSG" for the message, and created "BH5_Flow_M" for the value that will come from the MSG function. When I click the "..." button to bring up the config, I put the following in: Message Type: CIP Data Table ReadSource Element: BH5_FLOWNumber Of Elements: 1Destination Element: BH5_FLOW_MIn the PATH tab, i then put the following in: Path: LocalENB, 2, [iP ADDRESS OF SOURCE MACHINE]When I test the edits, I then get the ERR bit activate with error 16#0004 when the message rung runs. Anyone got any ideas where Im going wrong? I've practically copied another MSG instruction from further up the ladder but it doesn't seem to work

Ken Roach already answered this question for MicroLogix 1200, I'm trying to find the same answer for MicroLogix 1000. DF1 half-duplex communication gets dropped with MicroLogix 1000 slaves. I monitored the data, and found the slaves stop sending ACK, and the master stops sending ENQ. Slaves still send valid responses, but these responses are ignored by master because the ACK is not present. Power cycle solves the problem, but that's a hassle to drive out to remote sites. Power cycle to master sometimes solves the problem, but not always. Messages are initiated by the master, not by the slaves. Rockwell support said the only solution is to cycle power. Ken's approach was to monitor CS0:17, if it changes issue an ACL command. See previous topic: http://forums.mrplc.com/index.php?showtopic=22686 Thank you!

Hello, I am trying configure the communication between factorytalkview with ML1500, but the processor don't show in the tree. My connection PC to PLC is DF1 Serial, somebody could help me.

Hello guys, i would like to know if is possible keep always active the run command in a vf drive and for stopping the motor only send 0 reference. It´s possible??? because I want to program a ramp function in my plc for start and stop one motor. could someone tell me how to do this type of control please?.

Hi, I have a problem with my BC9020 and hope that someone can help me. I managed to set the IP adress of my PLC in the 10.2.5... add a root, run a program and make the PLC working for a while. I then tried another program, a new one... and now that I want to re-read the first program, Twincat System Manager doesn't allow me to enter in the "run mode" and stays in "config mode". It also has lost the IP address I set (10.2.5.....) and came back to the 172.16.22... (manufacturer settings) I cannot determine if the problem is in the PLC Control or In System Manager... This is my method to change the IP *** IP config *** 1) Reset the PLC First I place the end terminal next to the PLC. I set the DIP switches 1,6,7 to ON, power on the PLC and power off. I set the DIP switches 2,6,7 to ON, power on the PLC and power off. I set the DIP switches 1,2,6,7 to ON, power on the PLC and power off. 2) Set my PLC on the same AMS than my own IP (172.16.22...1.1) 3) In System Manager, add a new route 4) change the setting in I/O Configuration -> I/O Device -> Device 2(BX9000) -> clic on BX9000 define "set IP Address" to Manual define " IP Address" to 10.2.5...., the AMS change automatically. Press the configuration button and then Ctrl+F4 (run mode) This method worked but seems not to be the best... If you have any Ideas ? or questions? Thank you in advance Gregi

Can anyone help me with my PID issues, I can't seem to get them to work. The 3276 - 16383 represents the 4 - 20 mA scale. The 3153 - 15365 represents the actual values of a 4 - 20mA signal injected into the input. The 8761 represents the 9GPM required flow. Any help would be appreciated. Thanks in advance, Rojay PID.pdf PID.doc
