CC-Link master / slave station.
PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work A970GOT-LBA PDF A970GOT-LBA PDF A970GOT-LBA

Input / output points: maximum 256 points.
A scan cycle of PLC must pass through three stages: input sampling, program execution and output refresh.
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. Available netwwork: Profibus-DP A970GOT-LBA datasheet.
Function: Master station.
The A1SJ71PB96F and A1SJ71PB92D modules allow a PLC ANS to connect to the Profibus system,
Meet the CE standard, using SWOIX/ProfiMap special programming software.
A1SJ71PB96F compattible with Profibus-FMS, as a master or client;
A1SJ71PB92D compatible with Profibus-DP, can be used as a master to control the remote Profibus-DP I/O A970GOT-LBA datasheet.
