DELTA VFD MS300 PLC Function Applications (USING DELTA MS300 IN PLC MODE) ENGLISH

Introduction The commands provided by the MS300's built-in PLC functions, including the ladder diagram editing tool WPLSoft, as well as the usage of basic commands and applications commands, chiefly retain the operating methods of Delta's PLC DVP series. 16-1-2 WPLSoft ladder diagram editing tool WPLSoft is Delta's program editing software for the DVP and MS300 programmable controllers in the Windows operating system environment. Apart from general PLC program design general Windows editing functions (such as cut, paste, copy, multiple windows, etc.), WPLSoft also provides many Chinese/English annotation editing and other convenience functions (such as registry editing, settings, file reading, saving, and contact graphic monitoring and settings, etc.). Notes before PLC use 1. The MS300 provides 2 communications serial ports that can be used to download PLC programs (see figure below). 2. Channel 1 communications format is the same as channel 2. 3. Channel 2 has a preset communications format of 7,N, 2, 9600, ASCII can be changed in Pr. 09-01 (transmission speed) and Pr. 09-04 (communication protocol). 4. The PLC preset is node 2; the PLC node can be changed in Pr. 09-35, but this address may not be the same as the drive's address setting of Pr. 09-00. 5. The client can simultaneously access data from the drive and internal PLC, which is performed through identification of the node. For instance, if the drive node is 1 and the internal PLC node is 2, then the client command will be  01 (node) 03 (read) 0400 (address) 0001 (1 data item), indicating that it must read the data in drive Pr. 04-00  02 (node) 03 (read) 0400 (address) 0001 (1 data item), indicating that it must read the data in internal PLC X0 6. The PLC program will be disabled when uploading/downloading programs. 7. Please note when using WPR commands to write in parameters, values may be modified up to a maximum of 106 times, otherwise a memory write error will occur. The calculation of modifications is based on whether the entered value has been changed. If the entered value is left unchanged, the modifications will not increase afterwards. But if the entered value is different from before, the number of modifications will increase by one. Chapter 16 PLC Function ApplicationsMS300 16-4 8. When Pr. 00-04 is set as 28, the displayed value will be the value of PLC register D1043 (see figure below): Digital Keypad KPC-CC01 (optional) Can display 0~65535 9. In the PLC Run and PLC Stop mode, the content 9 and 10 of Pr. 00-02 cannot be set and cannot be reset to the default value. 10. The PLC can be reset to the default value when Pr. 00-02 is set as 6. 11. The corresponding MI function will be disabled when the PLC writes to input contact X. 12. When the PLC controls drive operation, control commands will be entirely controlled by the PLC and will not be affected by the setting of Pr. 00-21. 13. When the PLC controls drive frequency commands (FREQ commands), frequency commands will be entirely controlled by the PLC, and will not be affected by the setting of Pr. 00-20 or the Hand ON/OFF configuration. 14. When the PLC controls drive operation, if the keypad Stop setting is valid, this will trigger an FStP error and cause stoppage.
