How do I get my Symbol barcode scanner to work with ProSoft MVIxx-GSC or ProLinx ASCII solutions?

The RS-232 serial ports on most Symbol barcode scanners are RS-232TTL ports. RS-232TTL signal levels are lower than those of RS-232C ports, like the ones used in ProSoft solutions. Therefore, without some kind of adapter to boost the RS-232TTL signals up to RS-232C levels, these ...

When I increase the ReadData or WriteData array sizes in my program, all of the configuration parameter values go to 0.

When controller tag array sizes are changed in the ControlLogix platform, RSLogix5000 re-initializes all of the tags within that data type. This sets all values to 0 in all tags within that group. Before changing any controller tag array sizes, the user should record all configur...

How do I convert ASCII data to a Floating-Point value in a Logix based processor?

ASCII data acquired by the GSC module will be stored in the ReadString SINT (8 bit integer) array.This data can by copied to a string type tag, and then converted to a real (floating-point) value using the RSLogix 5000 STOR function....

Baud rate entries greater than 32767 in ProSoft Modules

Since RSLogix uses signed integers, the highest positive value that can be entered is 32767. To avoid this issue, when specifying higher baud rates, Prosoftmodules only require the first 3 digits of the baud rate. e.g., to enter a baud rate of 38400, enter 384. Use 576 for 5...

Do the serial ports on my MVI56 module provide any electrical isolation?

The two application serial ports provide 1000 volts of electrical isolation between the port and the ControlLogix backplane.The debug/configuration port provides no electrical isolation. Note: None of the ports provide any electrical isolation between the port and the module's i...
