TechTip: Enabling EasyAccess 2.0 on a cMT-GXX Gateway

The reduced interface in EasyBuilder Pro for the cMT-GXX series Gateway means that to start the EasyAccess 2.0 service we have to find a way to set the EasyAccess Control word LW 10820 to “1” to start the service. (At this point it is assumed that you have already purchased EasyAccess 2.0 and assigned it to your cMT-GXX gateway using PC Activator or the online service in on the web portal.)

The Macro below will set the required control word to enable the service:

macro_command main()
short EA2Enable = 1 // EA2Enable is a short (16bit word) and we’re setting it to “1” to start the EasyAccess 2.0 service

SetData(EA2Enable, “Local HMI”, LW, 10820, 1) // Set local word LW10820 to “1”

end macro_command

Be sure to either tick the box for “Execute one time when HMI starts”…

…Or use the System settings tick-box “Execute init. macro when power on”
