Analog Input Functions and Operating Procedures Section 2-6
Setting 0: Not used (the conversion value is reset when the bit turns OFF)
1: Peak value hold function is used (held while ON)
• CS1W-AD041-V1: Inputs 1 to 4
• CS1W-AD081-V1: Inputs 1 to 8
For the CIO word addresses, n = CIO 2000 + (unit number x 10).
In the following example, the peak value hold function is in effect for input
number 1, and the unit number is 0.
When mean value processing is used together with the peak value hold func-
tion, the mean value will be held.
As long as the peak value hold function is in effect, the peak value hold will be
held even in the event of a disconnection.
When the load to the CPU Unit is disconnected, the Peak Value Hold Bits.
2-6-5 Input Disconnection Detection Function
When an input signal range of 1 to 5 V (4 to 20 mA) is used, input circuit dis-
connections can be detected. The detection conditions for each of the input
signal ranges are shown in the following table. (see note)
Note The current/voltage level will fluctuate according to the offset/gain adjustment.
The following bits turn ON when a disconnection is detected in each input.
When the connection is recovered, these bits turn OFF. Be sure to specify
these bits in the execution condition of the ladder program when using the dis-
connection detection function in the user program.
