Make sure that the terminating resistances at the (other) ends of
the interface cables are activated. No resistances should be acti
-
vated in the base of the Q.gate. They are permanently fitted in
the Q.gate Test Controller and are always active.
Since the Q.bloxx modules plugged into the socket are only con-
nected to the interface UART 1 on the socket, they appear in the
Q.gate
Test Controller only for UART 1. In order to be able to use
UART 2 of
the Test Controller you have
to insert the Q.bloxx
Extension Socket QES; refer to Section 4.1.5, page 26.
The interfaces of the Test Controllers to the PC or PLC are acces-
sible at the front: Ethernet, USB and RS-232. You can in each
case only use one of
the Ethernet or USB interfaces at any one
time. Currently however, the USB interface cannot be used. The
RS-232 interface is used as a monitoring interface and is not suit-
able for the module configuration.
4.4.2 Connecting modules to Q.pac
The Q.pac Test Controller is inserted directly onto a mounting
rail (35 mm DIN rail according to DIN EN 60715) and connected
to the bases
via cables and plugs. If you want to exploit the maxi-
mum number of 64 modules, you must connect eac
h of all four
serial interfaces (UARTs) of the Q.pac to 16 Q.bloxx modules. The
sync lines are not needed and the synchronization takes place
through the UART lines. In doing this pay attention to the maxi-
mum line length of the individual interface cables; refer to the
table on pa
ge 31.
