14.7 Input Registers
These 16-bit input registers contain Analog (4-20mA) and Thermistor input readings.
Notes:
i
The input information is returned as 16-bit integers.
i Input Registers are accessible through Function Code 0x04.
Function Address DDE Ref. Purpose Data Format
Read (0x04) 0x0000 300001 Raw Analog Input #1 (4-20mA): STROKE
(J4-1, J4-2) WORD (0x0 – 0xFFFF)
[NOTE#1]
Read (0x04) 0x0001 300002 Raw Analog Input #2 (4-20mA): SPEED
(J4-7, J4-8) WORD (0x0 – 0xFFFF)
[NOTE#1]
Read (0x04) 0x0002 300003 Raw Analog Input: MOTHER BOARD
TEMPERATURE WORD (0x0 – 0xFFFF)
[NOTE#2]
Read (0x04) 0x0003 300004 Raw Analog Input: DRIVE BOARD
TEMPERATURE WORD (0x0 – 0xFFFF)
[NOTE#2]
Notes:
1. This is the Raw analog value returned by the 10-bit Analog to Digital Converter. Use the following
formula to yield approximate 4-20mA values:
a) Analog(mA) = RawValue*0.025
2. This is the raw analog value returned by the 10-bit Analog to Digital Converter. Use the following
formula to yield approximate temperature:
a) Temperature(C) = (RawValue*0.116538952) - 8.480204328
b) Temperature(F) = (RawValue*0.209770114) + 16.73563219
14.8 Holding Registers
The 16-bit holding registers contain display, keyboard, counters and various status and process variables.
Holding Registers are accessible through several Function Codes:
a) Function Code = 0x03 Read Holding Registers.
b) Function Code = 0x06 Preset Single Holding Register.
c) Function Code = 0x10 Preset Multiple Holding Registers.
Notes:
•
The input information is returned as 16-bit integers.
•
Reading a write-only HOLDING REGISTER will return the value that was written previously.
•
Writing to a read-only HOLDING REGISTER will NOT write and will NOT return an error.
