Figure 4 21 Note The ROC827 currently supports the HART module only when installed in slot 1 2 or 3 of the ROC827 base unit The HART module has four analog channels When configured as an input you can configure the channel for use in point to point or multi drop mode and typically connects to some type of transmitter such as for a temperature reading When configured as an output you can configure the channel for use in point to point mode only The output supports a Digital Valve Controller DVC Point to Point Mode In point to point mode digital communications are superimposed using the Frequency Shift Keying FSK technique on the 4 to 20 milliAmp analog signal which can still measure the process variable This mode allows communications with one HART device per analog channel Multi drop Mode In multi drop mode you can connect up to five HART devices in parallel to each analog input channel As with the point to point mode digital communications are superimposed on the 4 to 20 milliAmp signal However the analog signal is used only to measure the current consumed by the multi drop loop When all four analog inputs are in the multi drop mode the ROC827 can support a maximum of 20 HART devices The number of devices per channel is limited by the static current draw of the devices A ROC827 equipped with a HART module is considered to be a HART Host primary master interface with a Class 1 Conformance classification M
