Some devices are built with a fixed map that is defined by the manufacturer. While other devices allow the operator to configure or program a custom map to fit their needs.

Modbus is a communication protocol developed by Modicon systems. In simple terms, it is a way of sending information between electronic devices. The device requesting the information is called the Modbus Master and the devices supplying information are Modbus Slaves. In a standard Modbus network, there is one Master and up to 247 Slaves, each with a unique Slave Address from 1 to 247. The Master can also write information to the Slaves. See similar questions...

Enron Modbus is a modification to the standard Modicon modbus communication protocol developed by Enron Corporation. If you read this page, We would love to hear your comments.

Search by Keyword - search for "Texas", "Arrowsmith", "Geographical", etc. The search is case insensitive. View a much larger page that shows "all maps" or some other large category. As these pages are slow, the previous searches are preferable. See similar questions...

We provide a special kernel that runs our logic engine to interface with the non-compliant hardware. When our kernel is installed, it also includes additional Modbus drivers for supporting Modbus/RTU as master or slave as well as Modbus/TCP slave and master. We also support Modbus/TCP via UDPs, recommended for even more performance. See similar questions...

Two tables store on/off discrete values (coils) and two store numerical values (registers). The coils and registers each have a read-only table and read-write table. Coil/Register Numbers can be thought of as location names since they do not appear in the actual messages. The Data Addresses are used in the messages. See similar questions...

Our MODBUS Libraries are in use around the world in diverse applications which include mission critical applications also. A listing of some of them. The Indian Space Research Organisation (ISRO), which is responsible for building Satellites and launching them into outer space uses our MODBUS Libraries on several VMEbus based embedded controllers running the OS9 operating system.

Look through our Other Map-Related Sites pages for the maps you need. We also recommend using Internet Search Engines to locate additional maps. We find Google Image Search and Yahoo Image Search to be very effective. For example, you might use the words "map" or "maps" as part of your search, or the equivalent foreign language terms, along with the place name or keyword you are looking for.

The maps were usually too big for one scan. Sometimes there are slight color shifts between pieces when they are stitched together; this is rare. See similar questions...

The MODBUS Source Code Library comes in with a set of 'C' source and header files which contain implementation of the MODBUS RTU stack and the user portable code. The portion of the SCL that requires implementation by the end user is placed in a set of separate 'C' source and header file so that it is easier for the end users to selectively modify the SCL. This also avoids accidental modification of the MODBUS implementation by the end user. See similar questions...
