The Maple Systems Operator Interface Terminal (OIT) allows a Modicon PLC to call up a message that is stored in the OIT by using a “Message Request Register”. A 4XXXX Holding Register can be used by the PLC to tell the OIT to display one of its messages. For example, register 40500 is the default…
Allen-Bradley MicroLogix series / SLC500 series PLCs have some specific addressing format requirements for select memory locations (Bit-level and Strings, for example). Both drivers (Serial and Ethernet) follow these rules: Bit-level objects must reference the bit position to two digits! Bit 0 is 00, bit 9 is 09. For example, B3 memory, word 5, bit…
Yes, based on the model, you can download a project using a USB flash drive or SD card. See Tech Note 5087, “Download a Project to an HMI with a USB Flash Drive or SD Card” for more information.
Yes, select models allow users to view a live video web stream on a remote computer from a USB video camera attached to the HMI. This is useful for monitoring a process or area of the manufacturing floor that is difficult to see from the operator’s position.
Use Ethernet TCP Port 20248 to download a project to a HMI display.
Yes, to do this the PLCs on the network must all use the same protocol. When setup, the HMI project will automatically search for another PLC when communication is lost from a PLC that had previously established communication. If no PLC has communication established when the project is originally downloaded, the HMI project will not…
EtherNet/IP is an industrial network protocol that adapts the Common Industrial Protocol to standard Ethernet. EtherNet/IP is one of the leading industrial protocols in the United States and is widely used in a range of industries including factory, hybrid and process. The EtherNet/IP and CIP technologies are managed by ODVA, Inc., a global trade and…
Wide area network (WAN) is a telecommunications network or computer network that extends over a large geographical distance/place. Wide area networks are often established with leased telecommunication circuits, connecting multiple smaller networks like local area networks (LANs) and metro area networks (MANs). Unlike a LAN, which is confined to a single building or location, a…
Multiple Maple Systems OITs can communicate to a single GE Fanuc Series 90 PLC through a CMM module. The CMM311 module is available for the Series 90-30 PLC. The CMM711 module can connect to the Series 90-70 PLC. Each CMM module enables the user to install 2 additional ports running the GE Fanuc SNP Protocol…
