I’m having some trouble trying to save test data to a trend file. It's a E1151 HMI connected to an FX3U PLC (with 2 ADC's, and 1 DAC). I can get it all to work for a few lines but then it just stops, for no apparent reason. Has anyone else run in to this problem before? I have attached the trend setup, it starts to collect data but then just stops 5 lines in, half way though outputting the time, without an “End” statement or anything. It looks like it’s crashed or run out of memory, but I’m fairly sure there should be enough memory to store this. Example trend file. 28.09.16,16:09:40,0,34,6.8,0.200951,-0.00421429,0.0605635,7.53491,123456789 28.09.16,16:11:05,0,0,0,0,0,0,0,0 28.09.16,16:11:10,17227,0,6.8,0,0,0,0,0 28.09.16,16:11:20,17227,35,6.8,0,0,0,0,0 28.09.16,16:11:36,17227,35,6.8,0,0,0,0,223456789 28.09.16,16 Another example after I changed the sample count to 65534 29.09.16,11:47:23,0,0,0,0,0,0,0,0 29.09.16,11:53:33,17227,35,6.8,0.156296,-0.00648355,0.060258,7.53232,0 29.09.16,12:10:30,17227,35,6.8,0.156296,-0.00648355,0.060258,7.53232,0,OFF 29.09.16,12:11:07,17227,35,6.8,0.156296,-0.00648355,0.060258,7.53232,0 2
Hi all, I wonder if anyone can help me. I have 4 test rigs setup with E1151 HMIs and FX3U PLCs (with two ADCs and one DAC). They are running pretty well, and the HMI changes block fine when using Jump to Block, but when I try to get the PLC to change the HMI's block using the New Display Reg it becomes very temperamental. For automatic testing I want the PLC to prompt the HMI to change block, so I set it up with a PLC register, then set the HMI to use this register for the New display reg. When I turn the PLC and HMI on I can run through the test, and at the end it changes screen perfectly. However if I run the test again the HMI appears to "forget" to change screen. I have checked the new display register and It lists the correct screen, but the HMI doesn't change. So far I have tried adding "SCRR" too the command list to use short recipe names (saw this on a previous post), and tried reducing the amount to data transfer between the HMI and PLC to see if it was a latency issue, but neither have worked. Has anyone else witnessed problems like this?
