E

HAbility to download register data such as recipes to a Micro PLC. Comments can be used in the file, as in the following example, to describe the data being downloaded. In this example, data is sent to registers R100, R101, R102, and R103. To the application program in the Micro PLC, these registers represent paint color, number of widgets, starting serial number, and oven temperature.

HFinally, a Manual mode is available which allows you to poll a Micro PLC, and observe both the transmitted data (including header and checksum information) and the received data. This is valuable when you are trying to determine that the Micro PLC is actually sending the appropriate register or I/O data.

In Manual mode, you can also send data to the Micro PLC's register or I/O tables as individual words, and to the register table as a bank of up to 30 (typical) registers.
