The 1785-V80B is a 1785-V Series PLC-5/V80 VME programmable processor manufactured by Allen-Bradley. The 1785-V80B is a programmable processor which brings the technology of the 1785 PLC-5 processor to the VMEbus environment. It features an extended local I/O scan time per rack of 0.5 milliseconds. Communication is possible through the 4x DH+ or adapter/scanner ports, it has a backplane current load of 5 Volts, 3.3 Amps of current, and up to 1920 Analog I/O. The 1785-V80B VMEbus programmable controller is part of a chassis-based modular family that enables the operator to quickly and flexibly program and network with the I/O and other controllers to fit the users’ exact requirements. It brings together the current and future systems by use of a network such as the Ethernet/IP, DeviceNet, and ControlNet network. It also offers connectivity between SLC 500 and ControlLogix controllers.
To use the 1785-V80B processor as a remote I/O scanner, first, configure the remote I/O channel into the scanning mode to read and write I/O information between the 1785-V80B programmable processor and an I/O device that is remotely located from the controller. When it is set in the scanning mode, it acts as the supervisory controller for programmable processors which are in the adapter mode. When it is in the adapter mode, it does not require ladder logic in the adapter processor for block instruction transmission. The 1785-V80B has a backplane that provides a communication path between the I/O module and the I/O adapter module.
