I have a micrologix 1100 connected to crimson 3.0 using the emulator. I can read the output file and timer file fine, but cannot read the Bit file at all. I'm using the exact same setup. I have not used an hmi before and I'm wondering if there is some setup within the plc that protects the bit file? My tag is setup as follows: Source - PLC3, B003:0000 Extent: one item Treat as: Bit array Big-Endian Bit 0 manipulation: none Access: read only I have a similar tag using O000:0000, bit 0 and it works fine. In fact, I tried several different outputs and they all work. I tried to find something in Rslogix 500 that would preclude the Bit file from being read but can't seem to find it. Am I barking up the wrong tree?

Too funny!!! I remember it too... That still didn't do the trick. I know I'm missing something really basic. I thought AB treated the output file and bit file as high order bits first.... In Rslogix500 I am using the bit as: B3:0/0 Then in crimson, I'm calling it B003:0000 Bit 0

Thanks Sparky. I did have that problem, but found it after a couple of re-tries :)

I've been retired for many and just now coming back into PLC programming. I have NO experience using HMIs. In my first attempt I'm trying to connect an AB micrologix 1100. I have the following in place: AB Micrologix 1100 RxLinx classic RsLogix 500 micro crimson 3.0 and old Dell pc with one serial port and ethernet I have com1 configure as DF1-master I have an ethernet cable connected to the plc and configured. I can ping it fine so I think the connection is good. I can download a program from rslogix to the plc and it runs fine. I have configured a very simple control panel in crimson but I can't get the emulator to talk to the plc at all. I've been over the communications setting many times and just can't find anything wrong. I guess I'm lost as to how to troubleshoot it. I'd like to be able to verify that the communcations from the crimson emulator and the plc are working, but I can't seen to find a way to do that. Any help would be appreciated.

I did finally get it to work. I wound up using 'DF1 Master Via PCCC/EIP'. I had tried it earlier to no avail but I've probably fixed the real problem along the way and didn't know it. Thanks to all for your help. Sorry I can't give an absolute reason for the problem. I did try to go back to the DF1 Master' driver though and it does NOT work. I'm on build 459 of crimson 3.0

Thanks. I've tried both drivers. I also did find a big problem in that my plc did not have the ip address setup. I thought I had done it but it was blank. If fixed that with BOOTP and now it appears everybody likes the 1100. When I'm in crimson I can 'verify' link and it reports everything is ok. I have no errors. I've tried to just put up a couple of indicators. I've linked one directly to the plc output, the other I linked through a 'flag' tag. Neither one seems to be reading the plc. I'm going to try to capture some network data with wireshark...

Thanks. I did have that set already.
