AL#2: Alarm Output 3 Explanations: The settings for AL#2 are the same as those in AL#0. 5 Monitoring Functions 5.1 Monitor Bit Registers (MB) MB#0: Number of Devices Monitored Explanations: For setting up the number of devices to be monitored. Max. data in 16 slaves can be monitored. b15 is read only (Default =1: normally enabled cache mode) MB# (Odd Number): No. of Station Monitored Explanations: MB#1, MB#3, MB#5 … MB#33 are for setting up the station No. (0 ~ 255) to be monitored. MB# (Even Number): Address of Device Monitored Explanations: MB#2, MB#4, MB#6 …
MB#34 are for setting up the address of the device to be monitored. MB#201: Monitored Value Explanations: DVP-PLC Application Manual 13 MB# Attribute Content Explanation Default Latched 0 R/W Number of devicees monitored Cache mode normally enabled (b15=1), monitoring data in max. 16 slaves. 0 Yes 1 R/W No. of station monitored No. of the station to be monitored 0 Yes 2 R/W Address of the device monitored Recording the address of the device monitored. 0 Yes 3 ~ 32 R/W No. of station monitored, address of the device monitored No. of the station to be monitored; recording the address of the device monitored.
0 Yes 33 ~ 200 R/W Reserved 201 R Monitored value Every MB records the value in the 16-bit device. 0 No 202 ~ 213 R Reserved 214 R Monitored status Every MB records the status in the 16-bit device. 1 = normal; 0 = abnormal 0 No Symbol “R” refer to read only; “R/W” refers to read and write.
