Explanation
1. ADPEAK is dedicated for analog input modules (AS04AD-A, AS08AD-B, AS08AD-C, AS06XA-A, AS02ADH-A) to
enable and disable the recording of peak values. This instruction is available for PLC with FW V1.10.00 or later and
ISPSoft V3.13 or later.
2. Group is used to specify the analog input module connected to the right side of PLC directly or connected to the
remote module that acts as PLC, e.g. the PLC is number 0, the first remote module would be number 1 and so on.
The maximum group number is 15.
3.
Module: The module number that is connected to the right side of PLC directly or connected to the remote module
that acts as PLC, e.g. the first connected module is module number 1, the second connected module is module number
2. Up to 32 modules can be connected and counted and each type of modules should be included in the count.
4. ChNo: The specified channel number. Channel1 would be numbered 1 and channel 2 is numbered 2.
5. MAX and MIN are respectively the maximum value and the minimum value. When EN switches from OFF to ON, the
values of MAX and MIN would be initialized to a new measured value and start recording peak values. The values of
MAX and MIN would be updated continuously while detecting maximum and minimum values. If selecting integral to
be the format of output values of AD module, we suggest to use it with 16-bit ADPEAK instruction. If selecting floating
point to be the format of output values of AD module, you must use it with 32-bit DADPEAK instruction.
6. If En switches from ON to OFF, the function of recording peak values would be disabled. Meanwhile, the values of
MAX and MIN would be unchanged and would not be updated.

Description
This function is NOT available for this module.
The setting of group number or module number is incorrect.
The input value of the module is illegal or out of range.
There are no responses from the module. Communication timeout.
The channel cannot be found in AD module.
The channel designated by AD module is in progress of recording. Other channels cannot
perform the same task at the same time.
The data format of AD module and the instruction do not match with each other.
