The "group error signal" is set (= 1) of one bit of "processor status" (message 1:5, page 45) is set. Similarly, the "group warning signal" is set (= 1) of
one bit of "warning signals" (message 1:3, Seite 44) is set and "group fault signal" is set if one bit of "Tripped signals" (message 1:2, page 43) is set. An
additional option for releases N and P when used in conjunction with the communication module with measurement functions (Z=F05) is to apply the
"fault signals" (message 1:8, Page 46) to either the "group warning signal" (for OS1:2 = 0) or the "group fault signal" (for OS1:2 = 1) by means of
"additional functions 1" (message 1:121, Page 50).
