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...

What is the best ProSoft solution for communicating to devices that use the Siemens USS ASCII-based protocol?

MVI56E-GSC or MVI56E-LDM In-Chassis modules are recommended forcommunicating with any ASCII based protocol from a ControlLogix .  Thisassumes knowledge of protocol properties such as command and responsestructures, baud rate, data bits, parity, and other details of theprotoc...

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...
