RS-232C connection (QnA/A/FXCPU direct connection, computer connection, micro computer connection).
No clock function.
Applicable model: A956WGOT. Output type: relay output.
Output points: 16 points.
OFF leakage current: -.
Output protection function: No.
Rated load voltage / current: AC240V/2mA.
External connection: 2 wire A1SJ71UC24-R2 .
Type of input and output terminal.
Using 2 pieces of structure of the terminal units, maintenance can be maintained in the same line under the condition of the replacement module A1SJ71UC24-R2 Temperature sensor: PT100, 4 wire system.
The A1S62RD3 and A1S62RD4 temperature sensor input modules allow the platinum resistance temperature sensing element to be directly connected to the PLC,
This component converts a signal from a temperature measuring element to a numeric value that represents a temperature measurement value,
This temperature value can be used for the control process A1SJ71UC24-R2 .
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of A1SJ71UC24-R2 .
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on.
This phenomenon is called the I/O delay time effect. Program memory capacity 14K.
Input and output points to the maximum 512 points.
A scan cycle of PLC must pass throughh three stages: input sampling, program execution and output refresh A1SJ71UC24-R2 User's Manual.
PLC in the input sampling phase: first of all, in order to scan the sequence of all existing input latches in the input terminal of the state or input data read,
And write it into the corresponding input status register,
Refresh the input, then close the input port, enter the program execution stage A1SJ71UC24-R2 User's Manual.
