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 QD77MS2 PDF QD77MS2
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.
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 QD77MS2 PDF.
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 QD77MS2 PDF. "RS-232 1 channel.
RS-422/485 1 channel.
Transmission speed: 2 channels.
Total 230.4kbps.
Corresponding Configurator-SC Version2 GX.
Serial communication module capable of collecting and changing data of programmable controller, monitoring and managing, measuring data collection and so on.
Can achieve the highest speed of 230.4kbps, the maximum of 960 words (MC protocol communications) of the high speed and large capacity communications.
Can use MC protocol, through the external devices (PC, monitors, etc.) to implement the data read / write programmable controller.
By selecting a non sequential protocol and use sequential program for communication control, the programmable controller and the external device (barcode reader and measurement equipment),
Communication with local protocols using external devices.
QJ71C24N (-R2) through the RS-232 serial communication,
Programming and monitoring of programmable controllers using programming tools.
QJ71C24N (-R2) with the ffunction of the modem corresponding to the public telephone line,
Can be used to initialize the modem, and the connection of the object device processing,
Communication with a remote device, a programming tool, a modem, and a publiic telephone line QD77MS2 datasheet QD77MS2 datasheet.
Using remote password,
Can be prevented by QJ71C24N (-R2) function of the modem Q series programmable controller for illegal access.
