3 SPECIFICATIONS MELSEC-Q 3.5.44 Alert 1 to 4 mode setting (buffer memory address 192 to 195, 208 to 211: Un\G192 to Un\G195, Un\G208 to Un\G211) This setting is available in the setting mode only. To activate the change, turn on Setting change command (YnB). (1) The alert mode is set. (2) The values of Alert 1 to 4 are set in the following buffer memory addresses. • Channel 1: 38 to 41 • Channel 2: 70 to 73 (3) The correspondences between buffer memory addresses and channels are listed below. Mode setting item Alert 1 Alert 2 Alert 3 Alert 4 CH1 192 193 194 195 CH2 208 209 210 211 (4) The following table lists the alert modes and setting values. Refer to Section 3.2.10 for the alert functions of the Q62HLC.
