835555....3333....2222 Other tags in PMIU unitAll these tags except input tags are writable.Tag Type Format Range RemarksBit/Coil X xxxx 0000- 3100InputRegister XW xxxx 00000- 31015Mapped to physical Input of Expansion I/O units. In digitalinput, each bit corresponds to contacts. In analog input,each register is corresponding to input channel.Note that these tags cannot be written.Bit/Coil Y xxxx 0000- 3100OutputRegister YW xxxx 00000- 31015Mapped to physical Output of Expansion I/O units. In digitaloutput, each bit corresponds to contacts. In analog output,each register is corresponding to output channel.Data register D xxxx 0000- 4095Used for store various data. Each bit of register tag canused to bit/coil tag, but note that coil/bit addressed Dregister cannot use as operand of contact instruction inladder block.Bit/Coil B xxxx 0000- 4095Internaltag Register BW xxxx 0000- 0255Used for store various data. Each bit of register tag canused to bit/coil tag, and can used as the operand of ladderinstruction. If the value is written in register tag,corresponding bit/coil tags are changed.Device T.... xxxx 0000- 0255Timer device. When corresponding timer is ON, thecorresponding device changes to ON.Note that period is put behind T about timer device.TimerRegister T xxxx 0000- 4095Timer register (current elapsed time is stored). If time is up,corresponding timer device changes to ON.Device C.... xxxx 0000- 0255Counter device. When corresponding counter is ON, thecorresponding device changes to ON.Note that period is put behind C about counter device.CounterRegister C xxxx 0000- 4095Counter register (current count value is stored). If the valuereaches to preset value, corresponding counter devicechanges to ON.Index register I/J/Kxxxx 0000 Used for index modification. Refer 3.3.6. There is 3 registers(I 0000, J 0000, K 0000).Retentive register R xxxx 0000- 1399Data register of EEPROM area. Even if power of PMIU unitis OFF, the data in this memory area is not lost. Use tostore data that should be preserved even if unexpectedpower failure occurs and writing frequency is low. |
