To use the Electronic Signature option, you must purchase the option from GE and receive hardware keys with this functionality enabled. You must install the keys on both the SCADA node and on the iClient node. The application developer typically configures tags on the SCADA node, and operators typically enter electronic signatures on the iClient node. The keys are checked at run time, when an object whose tag requires electronic signature is selected. Both the iClient and the SCADA keys must have the Electronic Signature option enabled to use this functionality.
When the Electronic Signature option is enabled, you may be required to sign for actions you perform during run time. When the Electronic Signature option is disabled, you can perform actions without needing to sign for them.
Refer to Determining if the Node is Enabled for Signing for details on determining the status of the node.
