The 1775-MEA/A Error Correcting 64 KB RAM unit by Allen-Bradley is a PLC (Programmable Logic Controller) that monitors system input devices and the output devices. This device provides a real-time correspondence between output devices and input devices with accuracy. The PLC-3 controllers use Extended Addressing, which is a form of logical addressing. The expansion modules are made in such a way that they are transparent to the system. The 1775-MEA/A has no programming with expansions or additional I/O wiring.

The 1775-MEA/A is the part number whereas the specific model number is 1775-MEA Allen-Bradley PLC-3 and it weighs about 5 lbs (2.27kg). It inhabits one slot in a PLC -3 expansion chassis that can execute privileged and non-privileged commands. It also gives routing to the expansion bus that has 4 50-pin connectors. To link the intelligent RS-232-C to a local area network, the series works best with the 1770-KF2. The 1775-MEA/A PLC-3 controller is capable of accepting the PLC/PLC-2 type command messages with the PLC/PLC-2 logical addressing format. However, the user must allocate a PLC-3 input file first before this type of command may be sent to a PLC-3 station. The 1775-MEA/A makes use of physical addresses related to logical addresses. This is made possible by use of pointers. PLC-3 and PLC-5 controllers use physical addresses that are related to logical addresses by means of pointers. Since no two PLC-3/PLC-5 systems are configured identically, the pointers are not fixed.

The 1775-MEA/ It comes in different models all depending on users’ facility specifications and needs, and the available series range from 1755-MEA/A to 1755-MEA/Z. Being an error correcting device that relies on input vs. output data, this gadget improves users’ internal data and runs the facility efficiently. It is important to note also that the 1775-MEA/A comes with a manual for users and it lays out the steps for integration with other devices.
