Precautions Before Use

Precautions Before Use
Accuracy
When extremely sensitive temperature data is required, use the temperature data obtained 15
minutes after turning ON the FP0 RTD unit. (The temperature data obtained in the first 15
minutes is, however, within the total accuracy range.)
A rapid temperature change in the FP0 RTD unit might change the temperature data
temporarily.
A draft (air) created e.g. by a cooling fan built into the control panel and blowing on the FP0
RTD unit will lower accuracy. Avoid any kind of draft.
Programming
Between power ON and the first valid conversion data, the digital value will be 8191 or 16383.
When programming, be sure not to use the data obtained during this period.
When the RTD is broken, the digital value will change to 8191 or 16383. When programming
avoid any risks resulting from a broken RTD. A broken RTD needs to be replaced.

Always install the FP0 RTD unit the farthest to the right of the control unit.

Example for address assignment
The figure below shows the conversion data for the different channels. The I/O addresses
vary depending on the position of the RTD unit. In this example, the RTD unit is installed
directly next to the control unit as expansion unit no. 1, and WX2 and WX3 are allocated.

Conversion data switch flags
The analog unit has a 12-bit resolution. Before the data from the FP0 RTD unit is transferred
to the control unit, the data for WX3 is converted to 16-bit data as bits E and F are used as
conversion data switch flags. Data for WX2 need not be converted. (WX2 and WX3 apply if
the FP0 RTD unit is installed as expansion no. 1).
When the conversion data is negative, the data from WX2 and WX3 is represented as two's
complement: bits C to F of WX2 and bits C to D of WX3 will be "1".
After saving the channel information, the conversion data switch flags need to be masked.
They must be converted to "00" when the data is positive and to "11" when it is negative.
As resistor data is only positive, bit 0 to bit F for WX2 and bit 0 to bit D for WX3 can be used
to represent the resistance values.
Bit E and bit F for WX3 are used as conversion data switch flags. After saving the channel
information, the conversion data switch flags need to be masked. They must be converted to
"00" as the data is positive.
