  1. Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob. 
  2. I'm trying to replicate something I've done in an RSLogix5000 file without the usage of those convenient arrays.  I have 24 counters, for 24 hours in a day. I have a MapleSystems screen relaying this data in the warehouse. The logic I've tried to implement is as such If bit (HMI assigned for shift start) = 6 --------- Copy C5:78 to C5:130 with a length of ten. I'm trying to copy the 10 counters that will be displayed on the MS monitor into the part of the counters that are connected via tags. It's done like this so that if someone starts the shift at 8, it'll take from 8 + 10 hours into the same C5:130 ten registers to display it on any shift. When I copied c5:78 --> c5:130 w/ len:10 it copies the first value C5:78 into the tenth register C5:130, when I'm trying to have it copy those ten into the C5:130 starting ten, to display on the screen. What am I doing wrong here? It's as if that length of ten is acting as an indexer and if that's the case, do I have to do 10 copy lines for each hour I want to utilize this logic on? Thanks so much in advance!
  3. I've found very similar errors, but not exactly this one. Does anyone have any insight on how to remedy this? I'm using Factory talk and RSLogix5000.
  4. RsView32 doesn't connect

    Hi! I'm working with a VM with rsview32, rslinx and rslogix500/5000 inside; I can comunicate with all the PLCs in the net using rslogix and rslinx (IP). When I start my RsView project, it looks all in blank, I mean like RsView can't comunicate with any PLC, however I can program/go on line/download/upload any PLC using rslogix. I saw rslinx configuration and all the PLCs are available. Any suggestion?
  5. Hi guys, Im using RS-logix 500 Pro for configure plc AB Micrologix 1400 1766-L32B. I would like to seek some help for enabling data logging feature for this device. Im not even know how to start it. I really need some help here. Thank you.
  6. PLC filtering project

    Hey guys,   New PLC user here, and I've been tasked to control a filtering system with a PLC. I'm thinking about getting an Allen-Bradley PLC, but I don't really know what to look for when choosing a PLC. The system should have around 10 digital inputs, about 20 digital outputs, and at least one analog input. I don't quite know if I should buy a bigger PLC, or a smaller one and buy extra slots? Also, the digital inputs (sensors) are rated at 10VA. I plan on using a 24VDC power supply. My outputs are primarily comprised of solenoid valves. that are also 24vdc rated. Can anybody help me pick a particular model? Thanks in advance.
