Appendix 2: Use PLC-505 Serial

Functionality to Implement PLC

Remote Data Acquisition and

Program Update

PLC-505 has two user serial ports, so it can connect with PLCs that have serial

ports, and perform remote program download and transparent data

transmission. eYun platform and Vircom functionality make it easier to
implement remote access of PLCs that have serial port. Below we will illustrate

the implementation in detail.
