The PROFIBUS-DP interface enable communication withprocess control systems using the standard PROFIBUS-DP.Per device, up to 16 low-power solenoid valves can becontrolled and up to 32 sensor feedback signals can beread over the eldbus.The Type 3965-DPplus Valve Driver Modules are used tooperate external solenoid valves even with large K VS coef-cients.
The Type 3965-DP Solenoid Valve Island includes inline-mounted booster valves with smaller K VS coefcients in aexible modular design.Both devices are compact control units with integratedpower supply and gateway, allowing them to be used asstand-alone devices on site. Thanks to their low heat gen-eration, they are well-suited for installation in control cab-inets and for intrinsically safe applications.
Transparency from the eld level all the way up to thecompany levelThe Type 3965-DPplus Valve Driver Module andType 3965-DP Solenoid Valve Island integrate solenoid
valves and limit switches into the process control systemusing thePROFIBUS-DP protocol. This allows the state of theeld devices to be polled without delay. This powerful com-munication is the basis for the consistent ow of data fromthe eld level up to the production and company levels.
Fusion of operating and business datafrom the production environment
Analysis of operating data
Further information derived from the processsignals, including:n Control status (OK/error)n Opening and closing timesn Intermediate states (opening/closing)
Process signal logging, for example:n States (ON/OFF)n Diagnostic functions (open or short circuits)
Added Value Through Integration
Benets gained by exchanging dataThe integrated functions in the Type 3965-DPplus VaDriver Module and Type 3965-DP Solenoid Valve Islaallow the states and diagnostic data of eld units to bpolled over the PROFIBUS-DP network, which, for exple, considerably increases the efciency of plant opertion and reduces plant shutdown times and maintenanccosts.
