# Simple ESP library for Beckhoff ADS ## Features * Base functions * Ads Read * Ads Write * Ads ReadWrite * Convenience functions which are based on the functions above * Ads WritePlcVarByName * Ads ReadPlcVarByName * Ads ReadCoe (with and without complete access) * Ads WriteCoe (with and without complete access) ## How to install Download this repository as zip file and import it to the Arduino libraries. (Sketch -> Include Library -> Add .ZIP Library) ## Usage * Set WiFi SSID and password in the example .ino file * Set the SrcAmsAddr to the IP address of your ESP followed by `1.1`. * In the TwinCAT "Add Route Dialog" of the target machine you have to add the IP of this ESP. Make sure, that you have set the "Remote Route" to "None" ### Writing CoE Values Set the DestAmsAddr and the port in the code to the AmsAddr of the slave you want to access. ### Writing PLC variables Set the DestAmsAddr in the code to the AmsAddr of the target. This usually ends with `.1.1` Set the port to the port of your PLC. The first PLC usually has port 851 on TwinCAT3 and 801 on TwinCAT2. The port is also available as define. (`AMSPORT_R0_PLC_TC3`) ## Limitations To save some memory, the lib can read and write a maximum ammount auf 64 bytes. This value can be increased by overwriting the `#define ADS_MAX_DATA_SIZE` in ads.h ## Current status/To Do * The Lib is tested insufficiently * Should work with ESP8266, but not tested * The ADS Read, Write and ReadWrite function are mostly identical. With some affort this three functions can share the same code. ## Debugging * For some debug outputs on the serial console set `#define ADS_DEBUG_PRINT_ENABLE = 1` * DebugPrintHex() can be used to print a hex dump in a format like a hex editor
