MITSUBISHI Q172CPU Manual Q172CPU Common Instruction 1/2 Programming Manual

The input and output module installation number: 4.
Could extend the connection: not to extend the connection.
Application module: QS series module.
Security PLC (secure programmable system) refers to the self or external components or the implementation of the failure of the agency,
Can still respond to and promptly cut off the output of the programmable system Q172CPU Programming Manual.
Different from ordinary PLC, security PLC not only can provide the function of ordinary PLC,
Safe control function can be realized,
Meet the requirements of the ISO 13849-1 EN and IEC 61508 control system safety related component standards Q172CPU
PLC security market mainstream has oilz (Pilz) PSS 3000, PSS 4000,
PSS 4000 in addition to the security process can also be processed outside the standard control procedures Q172CPU Programming Manual.
All the components in the security PLC adopt the redundancy structure,
Two processor processing for cross detection,
The processing results of each processor are stored in their respective memory,
Output is only when the processing result is in full agreement,
If any inconsistency occurs during the process, the system is immediately shut down Q172CPU Programming Manual. "ABS serial synchronous encoder input can be used: 2 sets of modules / units.
Position detection method: compiled on value (ABS) method.
Transmission mode: serial communication.
Allows you to track target input points: 2.
Convenient processing of large capacity data.
In the past can not achieve the standard RAM and SRAM card file register area of continuous access,
The boundary of each area should be considered in programming.
The SRAM 8MB extension card is installed in the high speed universal QCPU,
Standard RAM can be used as a continuous file register,
Capacity up to 4736K words, thus simplifying the programming.
Thus, even if the memory space of the soft element is insufficient,
Can also be installed by the expansion of SRAM card, easy to extend the file register area.
The address register is extended to 32 bits, which can be programmed to go beyond the traaditional 32K word,
And to achieve the extension to the file register to all regions of the file register Q172CPU Manual.
In addition, the processing speed of the index modification plays an important role in the efficient operation of structured daata (array),
The speed has been improved Q172CPU Manual.
When the index is used to modify the program repeatedly (e.g. from FOR to NEXT), the scan time can be reduced.
