The full SLC command set functionality is available, and the unit is programmed with standard ladder programming tools (RS Logix and APS). The Modbus Slave protocol is enabled with the simple addition and setup of an Integer file at N100. This file configures the Channel 0 Modbus driver and allows user control over the operation of the port. In addition, extensive diagnostic data is returned from the driver to the integer file, allowing access to troubleshooting data. After the Modbus protocol is activated, a Modbus host can read and write data from all the common Modbus data types (binary in and out, analog in, and holding registers). In addition, support has been provided for the transfer of floating-point data, which optionally uses the 'Enron' addressing range. A host can also access the processor status file S2 to remotely monitor the health of the unit or to do such things as set the real time clock.
