ABB TP830-1 PLC module

Shell: The protection level of AC 800M and S800 I/O units is IP20, and each unit is individually marked with CE. If a higher IP level is required, an additional shell is needed; The use of additional enclosures usually does not affect the EMC characteristics of the controller; When installing the controller casing, in order to ensure good ventilation, a certain minimum distance should be maintained between the casing and the walls and ceilings; If the enclosure has a removable wall panel, it shall not be removed from any enclosure adjacent to any device that does not belong to the AC 800M controller and its connected S800 I/O; ABB recommends using RM550 (floor standing cabinet) and RE820 (wall mounted cabinet), with a protection level of IP54 and no additional cooling equipment required.

AC 800M unit installed on DIN rail: Due to the natural convection cooling of the AC 800M unit (CPU and communication interface), it can only be installed on a horizontal DIN rail; Each base has a locking mechanism that contacts the DIN rail with the metal backplate, providing an effective grounding connection. The DIN rail serves as the effective grounding for the system; The additional screw ears at the bottom of the base have no electrical function and can be used for additional fastening in environments with excessive vibration; There are two installation methods for the product in the cabinet, namely aluminum profiles with DIN rails or DIN rails installed on appropriately sized metal plates. The aluminum profiles or metal plates should be correctly connected to the protective grounding; Use DIN rails with a height of 7.5mm, referring to the NS 35/7.5 type of EN50022 standard; The interference suppression of external signals is usually directly grounded to the chassis and/or factory grounding, and the factory grounding potential must be stable and clear; The conductive backplate of each module is connected to a metal DIN rail as an electronic grounding conductor between modules, ensuring good grounding connection for internal logic, module EMI immunity, and RF transmission. The DIN mounting rail must have a good connection with the PE of the cabinet; If the AC 800M module is configured as two or more groups interconnected through extension cables, special attention should be paid to ensuring that all groups have good grounding connections for their DIN rails.

Configuration

General information: Using the engineering tool Control Builder, hardware (I/O and communication units) can be configured and applications can be created using control languages that comply with IEC 61131-3. The program can be compiled and run offline to facilitate process simulation before ultimately downloading the application to the controller. Control Builder provides a set of options, each with its own set of properties, simply select the option that is closest to the system requirements.

Connect Control Builder: Control Builder is installed on a PC and is usually connected to the AC 800M controller through the CN1 or CN2 ports on the control network and controller. It can also be connected through the COM4 port (RS-232C) on the AC 800M controller using tool cable TK212 and the serial port on the PC. In redundant configuration, Control Builder is connected to the COM4 port of the main CPU, and the backup CPU cannot communicate with Control Builder. PM851/PM851A is limited to one Ethernet (CN1) port and therefore does not support redundant Ethernet. The Control Builder standard does not support CI862, and to use CI862, appropriate system extensions must be installed. To use the FF HI function, the firmware of CI852 unit needs to be upgraded through the Serial Firmware Upgrade Tool. This tool loads special firmware with FF HI function into the controller and manually browses it in the Serial Firmware Upgrade Tool . Firmware Files SC860rFFHI folder and select firmware. ext.

Connecting to the control network: The control network is a dedicated IP network domain used for real-time data and general system communication between industrial computers, which can be expanded from small networks to large networks containing multiple "network areas" and hundreds of nodes. The controller is installed in the cabinet, and in industrial environments, AC 800M/control network connections must be converted to fiber optic (FO), which can be achieved by installing Ethernet switches with optical and electrical ports.

Communication possibility: The processor unit (PM8XX/TP830 or PM891) contains multiple communication ports, such as CN1 and CN2 for connecting to the control network, COM3 for RJ45 port with modem signal, COM4 for connecting to service tools, etc. By adding communication interfaces to CEX Bus, the number of protocols and processor unit ports can be expanded. The document lists the available interfaces and their quantities on CEX Bus.
