Activating the DPV1 Functions
The DPV1 functions can be activated in the parameter data (GSD, GSE). These functions are deactivated in the default setting. (Prm. byte 0 bit 15=1 activated, bit 15 =0 [default] deactivated)
DPV1 Functions
The IP/IL modules and the Economy Plus Bus Coupler (BK3120) support the following functions in the DPV1 services. The maximum length of the DP-V1 services is 48 bytes.
IP/IL configuration (IP-Link only)
The configuration of the extension modules can be read from the IP-Link coupler module. A word (of 16 bits) is transferred for each connected extension module (IExxxx). This contains the type of the module in the case of the analog modules, and the size and type of the digital extension modules.
