Multiple Output Circuit Control System; Valvue Esd Setup Options For Multidrop - GE Masoneilan SVI II ESD Installation And Maintenance Manual

Multiple Output Circuit Control System

®
ValVue ESD supports HART devices including, the SVI II ESD with non-zero polling addresses
and multiple SVI II ESDs on the same loop, for split ranging purposes.
To enable split ranging support through ValVue ESD the Multidrop function must be activated.
Activate multidrop on the Options screen, by clicking Allow Multidrop (Figure 85). If
unchecked, ValVue ESD looks for devices only at polling address 0. When in multidrop mode,
even if a device is found at polling address 0, other polling addresses are searched.
DCS systems offer multiple independent analog outputs driven by the same control signal to
solve the voltage problem with split ranged positioners. Use of such systems is recommended
®
for split range applications. The HART address of each SVI II ESD is 0.
