open; If the contact is open, the signal will flow through this contact.
Parameter
Parameter 1: register point parameter, in the form of X0.1.
Example
When signal of X0.1 or X0.4 is “0”, and X0.2 signal is “1”, the
current is conducted, with R10.1 being output.

Function
When PLC is turned on, the signal on the left of an element can always reach
the right through it. This function is usually used as the switch setting of
function module input, and used for those which need constantly valid input.
Parameter
No parameter.
Example
When the second input of counter uses true contact, the counting
starts with 1 after counter is reset; when the third input uses true
contact, the counter counts in continuous subtraction.

Function
Analog signal of temperature sensor is converted to digital signal by AD of IO module, and is
input to a positon (group number) of X register which is determined by device parameter of IO
module.
Parameter
Parameter 1: number of temperature sensor (number of temperature register). HNC-8 NC system
is limited to input of
20 temperature acquisition signals. Therefore, the range of values for
temperature sensor number is zero to nineteen.
Parameter 2: group number of X register corresponding to the digital signal of temperature
acquisition.
Parameter 3: thermocouple grid type (its default value is 0. 1: the corresponding model is built to
calculate temperature, by the user parameter specified by “parameter 4” which includes the lowest
and highest (the temperature corresponding to the voltage of 6.7 V) temperatures; 2: temperature
62
4. Basic function module
sensor of PT100 is supported, and thermocouple grid of HIO-1075 is connected; 3: temperature
sensor of KTY84-300 is supported, and thermocouple grid of HIO-1076 is connected; 4: the
relationship between the measured temperature and the resistance calculated by the entered value
of DA is linear. The corresponding model is built to calculate temperature, by the user parameter
(P parameter) specified by “parameter 4” which includes the lowest and highest temperatures, as
well as minimum and maximum resistances (unit: 0.01ȍ).
Note: The thermocouple grid type of 2 and 3 are standard configurations, where the corresponding
bus thermocouple grid can be connected, there are models of corresponding temperature in system,
and the value of P parameter doesn’t need to be set.
Parameter 4: set the range of acquisition temperature for temperature sensor by user parameter (P
parameter). As shown in the figure below, P30 specifies the acquisition for the lowest
temperatures, and P31 specifies the acquisition for the highest temperatures (the temperature
corresponding to the voltage of 6.7 V, unit: degree). If the thermocouple grid type is 2 or 3, set
value of P parameter will not be read.
TEMPSEN
0 X15
0 P30
The temperatures which have been gathered by No. 0 temperature
sensor, is put into X15 register. P30 specifies the lowest acquisition
temperatures.
