  1. hello guys, I've got a project and i am not too familiar with the allen bradley PLCs. So I hope you guys can help me with some ideas. we have a palitazer in our class we have to modify the PLC's program and add an extra fisical bottons, pause botton(red botton) and continue botton(green botton)  some times the operator needs to get inside to the enclosure WHILE THE MACHINE IS IN AUTO MODE and that is why we need the stop botton, so the operator can push it and "pause" the machine in any moment. all the outputs and inputs should stay in their current state until the operator press the start/continue bottom, after this the machine should be able to continue the routine.  here is some info about the palletizer  http://bidonequipment.info/pdf%20files/FMC%20CORPORATION%20EZY-150%20Palletizer.pdf I dont know if this is possible or not I've been studyng the ladder, but I could find the solution.  I atached the PLC program in this file, thanks you very much we got the PLC Allen Bradley SLC 5/03  How can I use Temporary End (TND) can this help?   if somebody want to see the PLC program (ladder) just let me know

  4. Hi there, I'm wanting to connect a panelview 800 to an SLC5/03 the SLC is connected to an 1747-AIC which is run to another 1747-AIC. I'm trying to figure out what cable I require to connect the peripheral of the second AIC module to the panelview. I can't seem to find any reference online. Any help would be appreciated. Image attached to clarify.    
  5. I need help in identifying the fault with a 1746-NR4 RTD / resistance module. The hardware is a SLC500 1746-NR4 module inserted into slot 3 of a 10 way rack, the processer is a SLC500 5/04   I have been using the RTD module to sample the temperature of a beer-brewing kettle and a fermentation enclosure, tone of the RTD’s was used to control the cooler, the second RTD was scaled through logic and controlled a temperature element through PID logic, this has been running fine for some time. Recently I returned from work and found that the CPU had faulted, the error was on slot 3 (RTD module), unfortunately I didn’t write down the error code, but I’m sure it was xx61, I know now I should have paid more attention to this code. When I cleared the error the processer ran perfectly with no new errors, what wasn’t right was that the heater in the fermentation enclosure was switched on due to low internal temp, when I checked the temperature readings of the RTD against a fixed gauge, the RTD’s value read 10 Deg C and the gauge read 20 Deg C.   I have scaled the RTD value directly, example I:3.0 on the first line of  SCP block and I can see the temp values on this line, I believe this to be an accurate reading. I have entered the correct configuration data in the channel configuration word, i.e. the correct bit settings, I have also tried to change these, example the data format values, the RTD input type, etc.   Convinced that the module was damaged I replaced it with a spare that I had and inserted that, this has now become corrupted or damaged too, and on this one I have lost 3 channels? Example; When an RTD element is connected to the module on channel 2, 3 or 4 the green light blinks, but when viewed in RSLogix the channels indicates that there is a device connected? When testing the range of the RTD in an ice bath the zero went to -4 Deg and in boiling water only reached 66 Deg c?   I have tested both of these modules on a different PLC rack, by swapping them out with a RTD module that I know is working ok. The same fault appears with the RTD modules in either rack and with two different CPU’s. I would like to be able to confirm that the rack or pane or rack isn’t faulty. At present there is only a D/O and D/I card in the rack.   Could this is a case that the modules require re-calibration? And is this an easy fix, can these modules be reset to the factory original spec? Do they require the firmware to be updated?   I would be grateful for any assistance that could be given as I am at a loss and I think I have exhausted all avenues
  6. I hope to be able to provide more information, but for now this is what I have. I have a SLC5/05 that faults whenever a graphic display is pulled up from a Cimplicity HMI. So, the PLC is not faulted while all harnesses are connected to the I/O modules, and while the Ethernet cable is plugged in, but it appears to fault when a corresponding graphic is called up that includes tags from the particular processor. There are two PLCs on the network, and I am not certain if they share data between each other or not, or if the data is just being shared to a common Cimplicity HMI. Another strange thing is that one of the PLCs on the network is using a MSG instruction to pull data from what appears to be the PLC that continues to fault, but the IP address configured in the MSG instruction does not match.
  7. Trying to add points to a QLC link from WDPF to SLC5/04, incorporating a 1770-KF2 DH+ interface module. This link has been in place for years, incorporating only DCS reads (both digital and analog). We recently added several more DCS reads successfully, but cannot seem to get digital or analog DCS writes to be seen by the registers in the SLC5/04 data table. Could this be a limitation by the 1770-KF2 module, or is there a more probable reason? SLC5/04 DH+---------1770-KF2---------QLC Could Duplex settings on the 1770-KF2 module have a bearing on this dysfunction? Successful DCS analog reads PT101, N9:2, A0000 PT102, N9:3, A0002 DP103, N9:4, A0004 Unsuccessful DCS analog writes PV101, N9:18, A0500 PV102, N9:19, A0502 PV103, N9:20, A0504 Any insight would be greatly appreciated. Thanks.
