junction compensation.
H0007
: CH7 is the external cold junction temperature, and the remaining
channels are all used compensated by using the temperature value of CH7 as
the external cold junction.
H0008
: CH8 is the external cold junction temperature, and the remaining
channels are all used the temperature value of CH8 as the external cold
jun
ction compensation.
 Example: to use the CH1 temperature value of host as the external cold junction compensation of other
channels, write the content [H0001] into the address [H0260]. The selection of CH1’s input can be PT100 or
thermocouple type.
 X indicates the internal station number of the host or measurement expansion module.
3.3.4 Input Channel Status
Reads the status of other functions of the system or measurement expansion module input channels; for
example, output of 1 and output of 2 indicate whether the function is on and whether the function is
performing self-tuning.
(Communications addresses and their content are as shown in the table below; channel status
corresponds to bit number: 0 =the function is off; 1 = the function is active)
Hx288 - Hx28F (input channels 1~8)
Corresponding function on/off (1 / 0)
Bit0 Alarm 3
Bit1 Alarm 2
Bit2 °C
Bit3 °F
Bit4 Alarm 1
Bit5 Output 2
Bit6 Output 1
Bit7 Self-tuning
