AI810 3BSE00851GR1 ABB Robot drive card module

Description

■ The cable length of AI810 3BSE00851GR1 connecting all baseplates in the system using remote baseplates cannot exceed 700 feet
■ Remote base plate cannot be used alone, it must be connected to the system with CPU. CPU can be configured in PLC or a person
Computer interface card in the personal computer (refer to Chapter 11).
■ Between the+5V logic power supply for the remote base I/O module and the interface circuit power supply related to the I/O bus expansion interface
The isolation device is installed to improve the remote expansion performance. AI810 3BSE00851GR1 isolation helps prevent problems caused by unstable grounding
Question.

■ The maximum number of remote substrates allowed for each system depends on the type of CPU used by the system. For CPU331340 and
341, the maximum number is 4. For CPUs of CPU350 or higher, the maximum number is 7.
■ Each remote base plate has a 25 pin socket D-type I/O expansion connector, which is installed at the right end of the base plate to connect other
Substrate.
■ AI810 3BSE00851GR1 remote base plate has two available specifications; 5-slot (IC693CHS398) and 10 slot (IC693CHS392).
■ The remote backplane does not support the following intelligent optional modules: PCM, ADC, BEM330, and CMM, which must be installed
On the CPU substrate, all other I/O and optional modules can be installed on any type of substrate.
■ The remote base plate has the same physical size as the expansion base plate, uses the same type of power supply, and supports the same I/O and
Optional module.
■ Each remote base plate has DIP switch for rack number selection.
Basically, the remote rack can provide the same functions as the expansion rack, but the effective distance is longer (700 feet/213 meters
Compared with 50 feet/15 meters of the expansion rack). AI810 3BSE00851GR1 In order to reduce the grounding instability, the remote base plate has additional insulation
The grounding instability may occur when the systems are far away from each other and do not share the same grounding system. however
However, distance is not always a problem; If the system grounding is incorrect, even if the racks are installed close to each other, problems will occur
Refer to Chapter 2 for grounding information.
The use of remote rack requires special consideration of relevant scanning time. To facilitate remote operation, when communicating with remote rack
When the I/O bus runs at a lower clock speed (compared with the expansion rack), the performance will be affected
Compared with other micro modules, such as high-speed counter or Genius communication module, the impact of discrete I/O is relatively small. Speaking of general
The scanning time and the additional time required for the template communication with the remote substrate are usually very small. More details on scanning time calculation
Refer to Chapter 2 of GFK-0467, Series 90-30/20/Micro PLC CPU Instruction Setting Reference Manual for information on.
Another consideration closely related to scanning time is the type of cable used for long-distance communication. Data transmission delay
Must be small to ensure correct system time and free time. Any type of cable that does not match may cause instability or
Incorrect system operation. The recommended cable type is specified in the data sheet of C693CBL300/etc. in the chapter “Cable”.
Mixed use of expansion and remote substrates in the system
The expansion and remote base plates can be used in the same system as long as the following requirements are met:
■ The maximum distance from the CPU to the last expansion substrate cannot exceed 50 feet (15 meters).
■ The maximum distance from the CPU to the last remote base plate cannot exceed 700 feet (213 meters).
■ Use the recommended cable model for the connection of the remote base plate of the whole system. The exception required at this point is 3
The foot (1m) long cable IC693CBL300 can be used as Wye adapter cable to simplify the daisy connection between substrates
Self made cable assembly of. For details of self-made cable used for remote base plate, please refer to the chapter “Cable”
Data sheet of C693CBL300/etc.
■ Termination requirements for expansion or remote systems.
When two or more baseplates are connected through the I/O bus expansion system, the I/O expansion bus must be completely terminated. The most commonly used terminal
The method to stop I/O expansion bus is to install a terminal resistor (IC693ACC307) on the last expansion or remote base plate of the system.
This resistor is installed inside the connection. Although the terminal resistor is shipped with each substrate, only the last substrate is on a link
The terminal connector needs to be installed on the board. Unused terminal resistors can be discarded. Pre connected 50 ft (15 m) cable
(IC693CBL302) A terminal resistor has been connected inside the connector at the end of the cable. If the system only needs one expansion rack and
And when 50 feet of cable connection is required (IC693ACC307 resistance package is not required in this case), this cable can be used
Ground, a self-made cable with resistance no longer needs IC693ACC307 resistance.
