Hello all, Can anyone explain me how to use Timer Instruction in Structured Text routine in RSLogix 5000? This instruction is not responding no matter how ever I try. I just want to use the Preset, Enable and Done bits of the time. Any help is appreciated. Thanks Kothy

Hi all, Folks I need some help here with RSLogix 5000. Create function SELECT for example: C:=SELECT(r:=s,p:=2,q:=3) + SELECT(r:=s,p:=4,q:=6); when 'r:=s' is true select returns 'p' else returns 'q'. So from the above example i donot create more variables. r,p and q are the only tags created and the select funtion will return the value wherever it is used. Can I do this in RSLogix 5000. I donot want to create more variables and hence I donot want to use a JSR. any help would be appreciated Thanks kothy

Hello all, Here is the problem im facing in RSLogix 5000. I have two DINT arrays for example TAG1 type DINT[32] and TAG2 type DINT[32]. Is there away that I can compare these two arrays such that when the expression is true to turn on an output? Please help. Thanx in advance. Kothy.

Hello folks, Has anyone tried to convert S7 program to an RSLogix 5000 program ? If so I would need help. Thnks in advance

Hi all, I have been trying to configure PLC5 on controlnet to use with Flex I/O but wasnt successful. Wonder if they are compatible at all. PLC5 finds all the FlexI/O modules through RsNetworx. But the RSNetworx file thats created is not seen in RSLogix5. The Flex I/Os are tied to 1794-ACNR/15 module. Am I missing any hardware? need help asap. thanx

Hello all, Problems with PLC 5/40 and PanelView1000. I am running in to some timing issues here between the PLC5/40(one rack no I/O cards) and the panelview 100 terminal using REMOTE I/O communication. The program has 12 block trasfer blocks. The processor seems to be taking more time as long as 5 to 8 secs to scan all these blocks which are cascaded in the program and write to the PanelView1000. Now initially i thought the above process is the root cause. But I tried a different program with only four block transfer blocks whcih took the same time. Now I am using a Belden Blue Hose cable which is around 2 feet in lenght and terminating resistors with it. Could anybody explain me why is the process taking so much time? thanks in advance kothy

I am trying to convert PnelView 1400e application to a PanelBuilder32 . I had to do the screens from scratch though, wanted to export the tag database but that sucker failed too. So i copied each tag to PB32. But B03 00/00-00/15 address as copied to PB32 says illegal addressing. is there any other format for the addresses in PB32? And also i need help with block transfers. The addresses in PanelView 1400e tagdata base look like these below B02 09/00-09/15 B03 00/00-00/15 and so on. I have the PLC5/15 program too. But I am not able to associate the BTR and BTWs with the addresses shown above in PanelView 1400e. I am using Remote I/O communication. please help me. especially with Block transfers. Thanks in advance kothy

I am trying to compare Function Blocks and Stuctured text programming. I mean the advantages and disadvantages. i wrote a small code in structured text and converted to function blocks and did not find much difference in scan times. So before i convert 100-200 lines of structured text code to function blocks, i would like to know which one is faster? and if so Why? Thanx kothy

Thnx for all the clues. A straight cable from PLC to HUB with the right Subnet and gateway worked. I can access the PLC froma different location . But here is the new problem, the connection stays only for certain period of time. I will have to shut down the RSLinx server and restart it to work and this continues. Any thoughts? Thanx

HalBishop, Thanx and here is the mising info: I have 1756 ENET/A tried using Ethernet devices and Ethernet/IP drivers Initailly i tried to communicate directly between my comp and the PLC by assigning private IP addresses with difference of one EX:162.14.12.1 to PLC and 162.14.12.2 to comp. this works. But it wont when i tried to put it on the network unless i dont have the right module or the right driver or either i am messing up the IPaddresses. kothy

Hi, I am tryin to put Controllogix 5550 on network, and access it from a different location in the plant. I tried the ETHERNET drivers available but I couldnt find the PLC. And moreover can we set our own address to the PLC? Also can i use a HUB to connect PLC to the network? Thanks kothy

Gerry, SEL function worked out. Thanx kothy

figured it out fellas thanx kothy

Hi folks, Can anyone help me reresent the statement below in Function Block? IF <A>=B> THEN <A=C>;provided all the tag types are real this might be simple but i am tired looking into instruction help and other resource I appreciate any help ASAP. thanx Kothy.
