Item
• Detects wire breakage for the connected thermocouple by
channel.
• Performs conversion enable/disable settings by channel.
• Sampling time may be reduced by disabling the conversion
at channels not in use.
• Designates sampling processing or travel average
processing by channel.
• The thermocouple type to be used may be set for each
channel or in batch.
• Designates the Pt100 cold junction compensation
enable/disable.
• By disabling the Pt100 cold junction compensation, a high-
accuracy ice bus is set outside of the module to increase
the cold junction compensation accuracy.
• Sets the upper and lower limits of the measured
temperature by channel.
• A value to one decimal place (16-bit signed binary) will be
stored in the remote register.
• The detected temperature value will be scaled to a value
of 0 to 2000 within the upper and lower limits and stored.
• Error compensation is performed by setting the offset/gain
values.
