How to work with special registers in a LCPU L0 structured project on GX Works2
Igor Lasmar posted a topic in Mitsubishi
Hello there, This is my first time here on this forum and also my first time working with this software and PLC. I am working off-line (since my PLC did not arrive yet) on GX Works 2, in a structured project type, with LCPU series and L02 type. the problem is that when trying to use any of the special registers (m8000, r23500, etc...) on my code after compile the error F1028 pops-up, on the other hand the same code with special register will work just fine in a simple project type without labels and I dont know how to make it work on my structured project with labels. -
Hello, I am trying to generate a wave form, such as sin, using mitsubishi's LCPU. The problem I met is that time precision of the wave form generated is only about 30ms. I checked my cpu scan time is about 2-3ms. my DA conversion specification is 1ms/channel. I am afraid CC-Link communication delay is the cause, but not sure. From the wave form, it seems some where time division is limited to about 30ms. I have expected at least for example 10ms can be obtained, i.e. if the period of my wave form is 100ms, I can output and get at least 10 data points. Would anyone give me some advice. Many thanks in advance. Ting Xing
