DNSvrCnxn:
This parameter is analyzed at power-on only.
It is the number of server connections opened simultaneously on the DGFC. As a first approximation the suit-
able value for this parameter can be calculated as follows:
1) DNSvrCnxn
=
0
2) if DGFC is slave in LocalBus, add X to DNSvrCnxn, where Xis the number of masters of DGFC. Increment
DNSvrCnxn by 1
3) if DGFC is slave in Explicit Messages add X to DNSvrCnxn, where X is the number of masters of DGFC.
4) if DGFC is slave in Predefined Mode add 2 to DNSvrCnxn, plus 1 if DGFC is not slave in LocalBus.
This parameter manages only the DGFC slave resources. This parameter does not take into account DeviceNet
resources. So, for example, you cannot configure the DGFC to be slave of 2 DGFCs in LocalBus and, simulta-
neously be slave in Predefined Mode, since this will require more resources than the ones provided by DeviceNet,
even if you set this parameter at 5.
Default value
=
3.
The following table sums up the various combination.
ONEnable DNSvrCnxn
1 LocalBus only 1 Set to 1 + the number of
masters (max 3)
2 Explicit messages only 1 Set to the number of
masters (max 3)
3 Predeflned Mode only 1 or 2 3
4 Predefined Mode and Slave in LocalBus
(of one master only) 2 4
5 Predelined Mode and Slave in LocalBus
~ofmore than one master)
Not Possible
6 Condition 1, 3 or 4 and DGFC slave in
Explicit Messages also
As condition 1, 3 or 4 Increase by the number of
masters
