When the key is in the protected position, program and configuration data can only be changed by a programmer connected through parallel communications (i.e., via the us ransmitter module). he status of the is indicated by the four green EDs on the front of the module. he 780 is used as the in a Hot tandby edundancy system. wo s are required in a Hot tandby redundancy system; one in the rimary and one in the econdary. Each of the s must be configured separately, with one configured as the rimary unit and one configured as the econdary unit. he location of the 780 modules in a typical Hot tandby edundancy system is shown in Figure 1.
