1.4.1 Classic Mode

In Classic mode (or Low Density) operation, the 2500C-8-TC operates logs in to the PLC as
an 8 word Input (8WX) module. Temperature values for each channel are reported to the
PLC in the corresponding input word. In Classic mode, the module accepts Type J
Thermocouple range. To operate the module in other ranges, you must change to Classic
Plus mode.
1.4.1.1 Classic Mode Module Default Configuration
The 2500C-8-TC ships in a default configuration which matches a common set of
application requirements.

1.4.2 Classic Plus Mode

In Classic Plus mode (or High Density) operation, the 2500-8-TC operates logs in to the PLC
as an 8 word input / 8 word output (8WX/8WY) module. Thermocouple or millivolt signal
values for each channel are reported to the PLC in the corresponding input word. The WY
output words are used to allow the PLC to select the input signal range for the module.
For example, if the module is in Classic Plus mode and is logged in at address 1:
WX1 = Channel 1 TC/mV Input
WX2 = Channel 2 TC/mV Input t
WX3 = Channel 3 TC/mV Input
WX4 = Channel 4 TC/mV Input
WX5 = Channel 5 TC/mV Input
WX6 = Channel 6 TC/mV Input
WX7 = Channel 7 TC/mV Input
WX8 = Channel 8 TC/mV Input
In Classic Plus mode, the PLC can select range operation from any of the following by
setting the appropriate bits in the corresponding WY word for each channel. In addition, the
PLC can enable or disable digital filtering, Scaling enable or disable, Degrees C or Degrees
F for each channel.
