Mettler-Toledo Serial Protocols for DeltaV

The purpose of this application note is to aid in the selection of DeltaV Serial Drivers for Mettler-Toledo weigh scales.

DeltaV Serial Drivers are available from MYNAH for several Mettler-Toledo Weigh Scales communication modes. In order to make sure that the driver you select is the right one for the application, please refer to the Mettler-Toledo scale user manual and the following guidelines.

• Multi-Continuous Output – specific to Jaguar scales and allows several Jaguar scales to communicate to one Jaguar controller that continually sends updates to the DeltaV Serial Card (read only).
• 8141 Protocol (also called Toledo Continuous Format) – master/slave driver where the DeltaV Serial Card can send tare, zero requests and read scale data.
• 8142 Protocol – similar to 8141 protocol.
