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…
In Tech Note 5084, “RSLogix 500 Symbols imported into EZware Tag Library” we describe the process for importing RSLogix 500 Symbols into the Tag Library. This Tech Note explains how to export a CSV tag file from RSLogix 500, use the AB Address Importer Utility to convert the tag file, and finally, how to import…
EBPro is used to Upload/Download from all current generation HMIs. To avoid any confusion, in all of our documentation: Upload means transfer the project file from the HMI to your PC. Download means transfer the project from your PC to the HMI. Downloading: Downloading a project is most commonly done using EB Pro. Go to…
Yes, live video can be viewed directly on select Advanced and cMT HMI products. Video input options are IP (Ethernet) cameras and USB cameras. Video cannot be recorded, but still images may be captured from the live video. Images are captured via a bit trigger, making this feature ideal for capturing production or security events…
By updating local memory registers on the HMI, you can change the PLC IP address, switching the HMI program to communicate with a different PLC over an Ethernet network.
If communication to one PLC is lost, the HMI has the ability to look for, find, and establish communications with another PLC. To do this, the PLCs on the network must all use the same protocol. If no PLC has communication established when the project is originally downloaded, the HMI project will not automatically search…
Ethernet is a family of computer networking technologies commonly used in local area networks (LAN), and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3, and has since been refined to support higher bit rates and longer link distances. Over time, Ethernet has largely replaced competing…
Our “MAC Address” Sample project shows what registers to display to find the MAC address of your Maple Systems HMI. The MAC address can also be found in the system information tab in the System Settings Toolbar (gear icon in the lower right corner) on the screen itself.
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…
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.
