A protocol is a complete set of instructions for a connected piece of equipment to perform its function. For example, for a controlled rate freezer, a protocol describes the change in temperature over time, as well as defining any alarm conditions.
To create a protocol:
Protocols -> Add a protocol -> Freezing Protocol
Protocols -> Add a protocol -> Thawing Protocol
NOTE New protocols are "Unapproved" by default. To synchronise a protocol to connected VIA Freeze or VIA Thaw equipment it must be approved by a user with the appropriate role. To approval a protocol check the box next to it and choose "Approve" from the "Selected" menu as shown below.
