Do you mean polling the I/O and internal variables? Definitely. The PLC has a full set of communication protocols that allows you to poll any data within the PLC. In addition, because it supports MODBUS protocol it can also be used as an RTU and polled by a PC SCADA program or HMI. If you want to write your own BASIC program you can refer to an example written in Visual Basic 6 at the following web link:

Isn't Qbasic a DOS program? If so, then there are already DOS sample communication program included in the TRiLOGI program CD ROM.
