It mention from register : 40256-40270 Alarm Code History Code ===== Description 01 ===== Pressure Sensor Failure 02 ===== Package Disch. Temp. Sensor Failure . . . 21 ===== High 1st Stage Disch. Temp. 22 ===== High 2nd Stage Disch. Temp. http://manualarchive.ingersollrandproducts.com/manuals/manuals/instructionbook/Misc_Manuals/80445596.pdf (from page 32 - 34) ======= It state : Code, not bit. Does "Code" transfer or convert as Value (Word) in Modbus reading? If in my ladder logic, I wrote / compare 1 = 1, the output bit0 = 1, it is alarm for Pressure failure actives. But then what happen if there are two Codes appear in the same time? Let's say, 1 and then 2 Codes alarm appear together. If the Code 2 appears last, and then the bit1 = 1 (Alarm for Temp) actives. And now how about the Code 1? The bit 0 indeed become = 0, since it is Code 2 (Value 2?), but actually there is still an alarm for Code 1 (Pressure) ...... ======= It really baffle me out, can someone help me ... ? Thanks alot, and warm regards.
