2-2 Understanding Configurable FLEX Ex Thermocouple/RTD/mV Input Module Features
Setting a FLEX Ex
Thermocouple/RTD
Module’s Operating
Status Input Type Select
Select the thermocouple or RTD mode for input channel groups 0-3
and 4-7. If 2 is selected, the module defaults to thermocouple. If 3 is
selected, the module defaults to RTD.
Range: 0 = thermocouple, 1 = RTD, 2 and 3 not used
Input type select for channels 4 through 7 use bits in word 1.
Sensor Type Select
Select the type of sensor for input channel groups 0-3 and 4-7.
Thermocouple mode 0 = mV, 1 = B, 2 = E, 3 = J, 4 = K, 5 = TXK/
XK(L), 6 = N, 7 = R, 8 = S, 9 = T, 10-15 not used.
RTD mode: 0 = W, 1 = Pt100 IEC 751 Amendment 2, 2 = Pt200 IEC 751
Amendment 2, 3 = Pt100 JIS C1604-1989, 4 = Pt200 JIS C1604-1989, 5 =
Ni100 DIN 43760-1987, 6 = Ni200 DIN 43760-1987, 7 = Ni120 Minco, 8
= Cu10 Minco, 9-15 not used.
If unused settings are chosen, diagnostic status “2 = configuration
failure” will be set, and the last valid configuration will be used. The
default = 0.
