20 EGD(Ethernet Global Data) GE Fanuc, Alston HPCi is representative, A lot of kind PLCs support EGD, PDA sample period may be 2ms. Below is an example of GE PACSystems PLC, install ME program soft. Create a new project, select logon PLC mode by right clicking Target1->property. PDA subroutine is called by the main program. A PLC PDA program is below. Add Ethernet Global Data component. PDA server may collect data from multi-producer of multi-PLC, You may distribute many producer to one PLC, EGD is identified by "Exchange ID", You may also distribute many IP to a PDA server. Establish first produced exchanges PDA1, produced period is 4ms. PDA1 sends 4 REAL 4 INT and 16 BIT. Establish second produced exchanges PDA2, produced period is 10ms. PDA2 sends 350 REAL, it may be an array, the array is of advantage to spares. Max 1400 bytes are supported by EGD. Config.csv is below, Data source type is 26, byte swap is not needed in PLC and PDA. You may packet PLC BOOL to WORD, BYTE should not be used.

Hardware configure may be downloaded when CPU is stopped. To modify EGD Exchange ID in the vicinity of the default value, otherwise it may cause Profibus-DP communication abnormalities. A boolean variable is defined on a particular bit of the register. To define some array such as REAL300, BOOL1600 for each acquisition data types is recommanded, these arrays are used to EGD configuration, It is easy to change the collection variables with same EGD configuration, and need not to restart the PLC, ST program directly transfer symbol variable to the array unit, ladder diagram "move" block is for address variable.
