The number of maps enabled simply limits the scope of map review so that you do not have to review a lot of unused
maps. If the displayed maps are used up and you need more, increase the enabled number.
7.3 BACnet Client Write Maps
Map number simply tells you where you're at on the list of register maps. Click "next" and "prev" to scroll through the
list. To advance directly to a specific map, enter the desired number in the "Showing" box, then click Update.
Maps entered on this page only write data to remote devices. Go to the Client Read Map to read data from those devices.
The full parameter set is different for read versus write.
An abbreviated version of a list of maps is shown on this page. Any of the parameters shown may be changed here and
registered by clicking the Update button. To view and/or modify the complete set of parameters, click on the map
number in the left most column.
Data from the local object given will be multiplied by the scale factor before being written. For each remote object to be
written, enter the object instance and type, and location (device). The names in the device list are defined in the Devices
page. The name is optional and used only for display purposes.
Selecting "none" for remote type effectively deletes the map even though it will still appear in the list until deleted.
Unused maps at the end of the list will always show none as the type.
Local Object is internally a coded number consisting of BACnet object type multiplied by 1000, then added to the object
number starting from #1. These are translated into abbreviations that are easy to interpret on the web page as follows:
AI n = Analog Input #n
AO n = Analog Output #n
AV n = Analog Value #n
BI n = Binary Input #n
BO n = Binary Output #n
BV n = Binary Value #n
MI n = Multi-state Input #n
