Abstract

A method for configuring a process control system includes coupling an I/O module to a PLC coupled to field devices. For each field device, the PLC has registers storing data of values associated with the field device. The PLC is configured such that each field device is associated with a PLC control tag, and each control tag is associated with tag parameters corresponding to the registers for the field device. The method includes configuring the I/O module to associate the tag parameters with corresponding controller parameters such that, for each control tag, there is a set of controller parameters associated with the tag parameters for the control tag. The method includes instantiating an integration object and associating the integration object with one of the control tags. The integration object configures itself, according to the set of controller parameters that is associated with the tag parameters for the control tag, as an analog input function block, a discrete input function block, an analog output function block, or a discrete output function block.
