PNOZ multi is a configurable safety controller with functions between safety relays and safety PLCs. It was born in 2002. Its purpose is to provide safety controllers with higher cost performance, easier use and more powerful functions for equipment in different fields. This product has been in mature applications for more than 20 years since its birth. It has been widely recognized by the market for its safety, stability and high cost performance. As an excellent safety hardware product, it needs to cooperate with safety configuration software to realize functions such as programming and diagnosis, and PNOZmulti Configurator software came into being.

From paid to free, there is more than a little progress

With each iteration of PNOZmulti Configurator, more models of products and practical security function blocks will be added. For versions V11.0 and above, basic authorization is free.

The newly added safety function block in the recently updated version of PNOZmulti Configurator V11.3 can provide a more professional safety and complete solution for the AGV (automatic guided vehicle) industry; a new safety bus communication module can make PNOZ multi products Quickly integrating into complex main control systems has a profound impact on the application level of products.

Three new function blocks of Configurator V11.3

1. Laser scanner switching area function block

This function can be used in conjunction with the PSEN scan security scanner to quickly generate logical functions for switching areas and improve the accuracy of area switching. At this stage, this function needs to be implemented with PNOZ m B1 / m B0.1 security hardware. Up to 4 security scanners can be configured in one system to achieve up to 70 area switching logical operations for each scanner, which greatly reduces the design effort of programmers. energy, providing a complete security solution.

2. Safety speed comparison function block

With the iteration of the version, the PNOZmulti Configurator software currently has a wealth of safety function blocks, and the safety speed monitoring function block has also been involved in previous versions. This update adds the safe speed/safe position comparison of two axes and the safe position/safe position range monitoring function block of one axis, which greatly improves the safety monitoring method under high-speed operation of the equipment. It should be noted that at this stage, if you need to complete the speed status comparison of the two axes, you need to use it in conjunction with the latest PNOZ m EF 2MM module.

Safety control logic is not limited to emergency stops, safety doors, light gratings, etc. In order to ensure comprehensive logic and reduce the frequency of malfunctions, monitoring such as speed range, speed difference, position range and position difference need to be configured together to ensure monitoring The results are accurate so as not to affect the operation of rotating equipment. To put it simply, the standard motion controller is used to control the operation accuracy, while the safety motion controller (1/2MM) is used to monitor whether there are abnormalities in operation to achieve precise braking.

3. PNOZmulti FSoE master safety bus module and communication function block

FSoE (Fail Safe over Ethercat) protocol is a secure Ethernet protocol developed by Beckoff based on IEC 61508. It is a technology certified by TÜV and internationally standardized by IEC 61784-3. Functional safety is a characteristic that industrial automation equipment must have to ensure personnel and production safety. Communication security is also a part of functional safety. Therefore, the emergence of the FSoE protocol ensures the safety and reliability of data communication.

The PNOZmulti FSoE master communication module launched in version V11.3.0 allows the PNOZ multi control system to quickly and conveniently connect to the original EtherCAT network to achieve an effective combination of standard control and safety control. The PNOZmulti FSoE master communication module can serve as a master station in the entire safety network to allocate tasks to slave station devices, and can also serve as a slave station to accept tasks assigned by the master station. The communication module is compatible with standard EtherCAT communication and also integrates the secure communication protocol FSoE. With the basic unit of PNOZ m B1, it can also realize Modbus/TCP or TCP/IP standard communication functions.

At this stage, you need to pay attention to the version restrictions. It can only be connected and used with the basic unit of PNOZ m B1 ≥v1.10 version. The configuration software needs to use PNOZmulti Configurator ≥v11.3 version.
