Hello everyone, I am working on building a PanelView C1000 program and created tags with direct addressing to the PLC I/O Example: Tag Name: PB_1 Address: I:0/0 Data Type: Boolean Controller: PLC-1 Tag Name: LED_1 Address: O:0/0 Data Type: Boolean Controller: PLC-1 I receive the following when attempting to verify the tags. ID: 3015 Type: Warning Message: Tag PB_1 with address I:0/0 has either an unknown address, unacceptable data type or undefined controller name. ID: 3015 Type: Warning Message: Tag LED_1 with address O:0/0 has either an unknown address, unacceptable data type or undefined controller name. This message only appears when I use direct I: or O: addresses. All other bit level addresses work fine. My questions are: Should I be using a different data type when addressing I/O directly? Do these HMIs support direct I/O addressing? Do I need to create a bit level address in my PLC program for each I/O I am monitoring? Seems rather redundant... Any advice would be most helpful. Note: I have looked through the Quick Start guide for addressing and no direct I/O addressing is used in their examples. They do not specify whether it is possible or not. Thanks again!

Excellent, thank you both for your help. This answers my question.

Hello Everyone, I managed to find out the differences between the Starter, Standard and Professional editions of the software packages for RSLogix 500 but I received pricing for both standard activations and concurrent activations. The concurrent licensing seems to be more expensive but I cannot for the life of me find anyone to explain the difference between the licenses. I know concurrent means "simultaneously" or "at the same time", but don't really see what they mean by this. Any insight would be extremely helpful. Also, Rockwell Customer Support wanted to charge me to tell me the difference between software versions I wish to purchase... I find it odd that they want to charge me to give me information to purchase a product from them... Thanks! Craig Chamberlin

I was asked this question about three hours ago by someone who called in and I am having difficulty coming up with a method to actually do this. He would like to issue an enable (set a register on a remote Ethernet supported drive to on) using a Micrologix 1100 drive with built in Ethernet. I have attempted to open RSLogix 500 to duplicate a scenario in which this is possible but cannot seem to have any luck with it. I do not have an option to click a "communications" tab when creating the MSG block so I can specify the IP address of the drive. Could someone specify a document that may aid me in this? Or specify whether or not it is even possible? I would really appreciate it. I don't mind doing the leg work if someone can just point me in the right direction. Thanks in advance!

I am attempting to transpose an old Micrologix 1200 program to a newer Micrologix 1500 processor. I was surprised to find out there was no F8 data file, nor can I create one through the menu system. There must be a way to get floating point accuracy with the Micrologix 1500 I have. I must be doing something stupid. Any help would be much appreciated. Craig Chamberlin Precision Electric Inc.

Hello everyone, The reason this question comes up is because my catalog claims it will only support 12 to 24 volts... but it says the same about the Micrologix 1000 and I have had success with it reading it before. Has anyone actually been able to work with a 5 V input on the 1200 with success? Please advise.

You're the man! I cannot believe I didn't catch that part in the chapter (it is in the about section) and is rather obscurely discussed. I really appreciate the response. Thanks again!

Hello everyone, I have been attempting to connect a Dynapar 600PPR encoder to the high speed input on my Micrologix 1000 PLC. According to the manual, this is I:0/0 and it is rated for 8KHz. I did the following math to ensure I was within that frequency range. 600 RPM Max Speed / 60 Seconds = 10 Rotations per Second 10 Rotations per Second x 600 Pulses per Rotation = 6000 Hz 6000 Hz / 1000 = 6 KHz This should give me a 2KHz leeway. According to the Micrologix 1000 Manual (Chapter 12) on High Speed Counters and the Help Section of the software, configuring the high speed counter to count pulses requires placing the HSC logic on a rung with no conditionals. I have done this. The program I created has only this counter to test my encoder input. Channel A of the encoder is wired to Input 0/0. The encoder is powered with the local 24 volt power supply from the Micrologix. This issue: When I download the program and place it in run, the counter can only count at the same rate as a regular counter (to test this theory, I placed a regular counter below it, wired channel B to input 0/1 and it counts at the exact same speed) For some reason the HSC isn't utilizing itself as a hardware counter. Now I've been digging through manuals for instructions for hours to try and find out why the counter will not count my pulses fast enough. Now I am assuming this is some stupid small setting I do not have configured properly. My Hardware: Dynapar H42-0600 Encoder Micrologix 1000 1761-L16BWA I have attached a copy of my program to this post. Any help would be much appreciated, I'm ripping my hair out this morning :D Thanks again! Craig Chamberlin Precision Electric, Inc. HAMPTON ML1000 REV 2.RSS
