The address registers of the IEC64 protocol are SPTB, SCNA, DPTB, DCNA, METF, and SENC. This was introduced in a fairly recent version of GX Works2 and is only possible on FX because only FX has the "one program file" limit in the CPU.1) Enable HMI Ethernet in ġ) Connect with PLC, select Ģ) Set IP address, it is the same LAN parameters with HMI ģ) Save PLC communication parameter, and restart PLCġ) Connect with PLC and choose to “online” modeģ) During monitoring bit address,1 pts should be selected during monitoring word address, 16 pts should be selectedĤ) Enter the register address, click OK to view the value of the register.ġ) Both word registers and bit registers support even continuous read/write functions Ģ) The range of registers is based on the specific PLC type In that case, the compiler will join these POU's into one MAIN program file before downloading it into the cpu. In that case, Mitsubishi introduced something called "program linkage order setting" which allows you to join a number of simple ladder POU's (up to 256 i think). It has to be noted that Mitsubishi introduced a solution to this problem which allows multiple simple ladder POU's inside one MAIN program file IF you upgrade your project from simple ladder to simple ladder with labels (and therefor introduce a compiler stage).
Upgrading to structured program will not help if you want your POU to remain in simple ladder (and not structured ladder) since it will have the same limitation. I don't understand how you managed to import an FX3U program from GX Developer into GX Works2 which has more than one POU (Abart, ERRORS_G.)? In simple ladder (GX developer), an FX3U program can only have one POU called MAIN because there can only be one "program file" in the CPU called MAIN.
