Embedded fieldbus
Activate bypass control functions – EFB
Controlling the bypass
Fieldbus control of various bypass functions requires configuration to:
• Tell the system to accept fieldbus control of the function.
• Define as a fieldbus input, any bypass data required for control.
• Define as a fieldbus output, any control data required by the drive/bypass.
The following sections describe, at a general level, the configuration required for
each control function.
Start/stop control (System)
Using the fieldbus for start/stop control of the system requires:
• Bypass parameter values set as defined below.
• Fieldbus controller supplied command(s) in the appropriate location. (The
location is defined by the Protocol Reference, which is protocol dependent.)
• Control commands must be addressed to the Bypass node with parameter 1625
set to 1 (SYSTEM). For DRIVE ONLY control refer to Start/stop control (Drive
only) on page 85.
