HMI INTERFACELRX P01 is an HMI operator panel, used with many types of PLCs or other intelligent controllers equipped with communication port. By using the HMI, the values of both PLC inner registers and relay status can be monitored and changed with the keys or LEDs. In this way, machinery and equipment functioning results to be simple and direct. The LRX SW P01 editor software permits to make dedicated screens by taking advantage of the graphic display to view bitmaps, bar graphs and trend lines. 19-3 Micro PLCs 19 O PERATOR PANEL COMMUNICATION MODES BACKLIGHT 192x64 PIXEL GRAPGIC LCD LRX P01 supports Modbus®-RTU protocol and different communication modescan be chosen, such as RS232 and RS485.

The power supply canalso be used to power eventual 24VDC auxiliarycircuits. – The LRX M00 backup memory allows to save the user’s program and to simply and quickly transfer itto the base modules. LRX P01 panel general characteristics– 24VDC power supply– RS232 communication port: • Direct connection to using LRX C00 • Connection to other devices using a standard D-SUB 9 serial cable – RS485 communication port– LRX SW P01 editor software for specific pages and easy use. FUNCTIONS– Send commands– Read status– Provide static and dynamic texts– Write variables– Read variables: • Numerical value• Bar graph• Trend line. ProgrammingAt any time and with extreme simplicity, can be set up and reprogrammed to satisfy new requirementsand improve the operation of a system.Programming is simple and intuitive and can be donedirectly on the base module keypad or by personalcomputer, connected by LRX C00 interface and using therelative LRX SW software.With a personal computer, two programming languagelocs can be used: FBD (Function Block Diagrams) andLADDER (contact scheme).Both of the following can be accomplieshed:– Simulate the program directly “off-line” on a personal computer to test if it runs correctly. – Use the supervision mode to check the project “on-line”. There are 8 function keys on front, dedicated to on-board adjustment, control and supervision of digitalinput and output status, analog input values, time anddate entry and the operation status of the itself.
