The Allen-Bradley 1785-L80C15 is a processor module with an integrated ControlNet interface for PLC-5 programmable controllers. The module is installed in the left-most slot of a 1771 I/O chassis. The 1785-L80C15 provides 100K words of user memory and support for up to 3072 I/O (any mix) or 3072 inputs or 3072 outputs (complementary). The program scan time specifications for the bit logic are 0.5 milliseconds per K word and typically 2 milliseconds per K word. Memory modules compatible with the 1785-L80C15 include the 1785-ME32, the 1785-ME64, and the 1785-ME100. The modules for I/O which are compatible with the 1785-L80C15 include the 1771 I/O, 1791 I/O, 1746 I/O and the 1794 I/O.
The data transmission rate supported by the ControlNet interface on the 1785-L80C15 is 5 Mbps. Specifications for the NUT (Network Update Time) are 2 to 100 milliseconds (configurable). Without the use of repeaters, the ControlNet network supports up to 48 nodes per link, while the use of repeaters increases the supported number of nodes per link to 99. Remote I/O and DH+ interfaces on the 1785-L80C15 support the following I/O scan times per rack: 10 milliseconds at 57.6 kbps, 7 milliseconds at 115.2 kbps, and 3 milliseconds at 230 kbps. A serial port is also available on the processor module. The 1785-L80C15 draws 3.3 Amps of current at 5 Volts DC from the chassis backplane. The heat dissipated during operation is 59 BTU/hour. The working temperature range is from 32 to 140 degrees Fahrenheit and the storage temperature range is from -40 to 185 degrees Fahrenheit. The module requires 5 to 95% relative humidity for optimal performance. The weight of the 1785-L80C15 module is 3 pounds.

About 1785-L80C15
The 1785-L80C15 module is a PLC or programmable logic controller module from the Allen-Bradley/Rockwell Automation PLC-5 series. One of the most distinguishing features of the 1785-L80C15 PLC module is its integrated ControlNet interface that allows it to communicate easily with the vast majority of other industrial machines and other types of controllers. This module can store up to 100,000 words of data in its user memory and it can support either 3072 total forcible I/O in any mix or 3072 forcible inputs and 3072 forcible outputs in a complementary format. If the I/O are not forcible I/O, then the 1785-L80C15 PLC module can support as many as 50,176 I/O at 1 time. This module does not have protected memory, but it does support RAM with battery backup and EPROM modules for backing up programs.
The Allen-Bradley/Rockwell Automation 1785-L80C15 PLC-5 module can transmit data at a rate of 5 Mbps through the ControlNet interface. Its network update time can be configured at anywhere between 2 and 100 milliseconds. The 1785-L80C15 module can also support 48 nodes maximum per link through its ControlNet interface if it is not using repeaters, and if it is using repeaters, it can support up to 99 nodes per link through its ControlNet interface. In addition to the ControlNet network, this PLC-5 module can also communicate through the DH+ network and the Remote I/O network. The 1785-L80C15 PLC-5 module operates in a temperature range of 32 to 140 degrees Fahrenheit, and it can be stored or transported in a temperature range of -40 to 185 degrees Fahrenheit.
The Allen-Bradley/Rockwell Automation 1785-L80C15 programmable logic controller module is part of the Allen-Bradley PLC-5 series. It has a ControlNet interface and it also supports the Remote I/O and DH+ networks.
