The Allen-Bradley PLC-5-40C is a ControlNet PLC-5 processor. It is used for controlling various modules and for information and data processing. It includes a ControlNet port for high-speed communication which features both peer-to-peer communication and I/O control faster than the DH+ and universal remote I/O network. The PLC-5-40C requires a one-time configuration for communicating with 1771 I/O modules via the ControlNet network, eliminating the need for block transfer programming. It also supports communication through standard ports that includes 2 DH+ or Remote I/O (Adapter or Scanner) port and 1 serial port configurable for RS-232, RS-423, and RS-422A communications. The PLC-5-40C processor requires a backplane current load of 3.3A at 5V and has a maximum heat dissipation of 59 BTU/hr. It has up to 48K of user memory with a limit of 32K words per data-table file. It has up to 2048 total forcible I/O (any number of the I/O can be inputs or outputs) with 2048 complementary inputs and outputs. It also includes 48,000 non-forcible I/O available only as ControlNet I/O. The PLC-5-40C has an average ControlNet I/O scan time per rack of 0.5ms which is much faster than typical I/O scan time of 10ms at 57.6 kb/s, 7ms at 115.2 kb/s, and 3ms at 230.4 kb/s. It requires one left-most slot for installation in a 1771 I/O chassis with keying bands between pins 40-42 and 54-56 for fixing that slot. The PLC-5-40C has EEPROM-based memory modules and battery-backed RAM for data backup. For troubleshooting and diagnostics, the PLC-5-40C processor has programmable fault response to prevent the system from crashing. For data processing, it uses the familiar ladder-logic. The PLC-5-40C also includes various other features such as advanced instruction sets, a timed interrupt routine, LED status indicators etc.
