**) The ISDUs 184-186 are available from firmware V19. For the variants with the option
“Modulo
function
” (i.e. variants with the feature “Software modules” = “M” or “Z”), the modulo function is
configured with these ISDUs. For the variants without modulo function (i.e. variants with the
feature
“software modules” = “1”, “S” or “P”) only the default value can be written, other values
are rejected.
