IC693CPU374 Central Processing Unit (CPU)

The uncertainty of IC693CPU374  to complete the localization upgrade on schedule is specifically divided into technical uncertainty and construction uncertainty, and technical uncertainty includes the uncertainty of the application level of the control platform and the uncertainty of the degree of understanding of the operating logic of the control object. Program 1 incorporates the control program of S5 into S7 PLC in the form of hardware and software modules, without changing the program flow, and fully meets the requirements of the buttons, sensors, main motors and other control objects connected to S5.

IC693CPU374 and the main motor and other control objects such as low-speed requirements, wiring construction is small, there is no key hardware performance of technical uncertainty and wiring connection on the construction uncertainty, as well as the degree of uncertainty in the understanding of the logic of the operation of the control object; Program 2 to replace the outdated PLC with a mainstream PLC system of the same brand, the implementation of the risk is not much different from the program, and even a little bit smaller; Program 3 of the hardware Changes in hardware and software changes are larger, both technically and construction, especially the control object operating logic to understand the degree of uncertainty are greater.

IC693CPU374 on the motherboard to increase the need for I / O cards, that is, two 32-bit digital input card (6ES7 421-1BL01-0AA0), a 32-bit digital output card (6ES7 422-1BL00-0AA0), and will be the original S5-95F PLC on the wiring connection in the corresponding position of these three I / O card, according to the slot location, in STEP 7 for each I / O O is assigned an address in STEP 7. In order to ensure the safety and reliability of the system as much as possible, the two independent sensor signals (safety information such as safety cover) originally connected to the master and slave S5-95F PLCs are connected in series to the corresponding inputs on the I/O cards.
