Digital Outputs OUTx
The digital outputs are programmable to operate from any internal signal. These signals include the
digital input states, status conditions (running, paused etc) and any fault conditions that are detected.
This makes it easy connect into other systems.
Communications & Display
Comms
RS232 and RS485 ports are available. These are used to connect ModWeigh units together and also to
connect to other systems. The protocol is either ASCII output for example to drive a printer or Modbus
for interactive communications. Baud rates and node addresses are programmable.
USB host and device ports are available. This allows for example PC and USB flash drive connectivity. It
can be used to update the units software, for data logging and for recording of the units settings.
Printouts & Macros
Printouts can be triggered by a key press or set up to occur at set times during the day or week. Data
may also be output continuously for data collection purposes. Data is output on the COM1 RS232 port.
The content of the printouts is fully programmable using Macros.
Macros are programs used to customise printouts, but can also be used to perform arithmetic calcula-
tions. The Macro language also contains conditional terms for more advanced programming.
Display Customisation
Locks may be set to prevent unauthorised use of the operator keys and restrict entry to the operator
menu. The keys are individually lockable and optionally a passcode can be used to allow authorised op-
erators to use the keys. Alternatively a confirmation of the key action can be requested.The operator
MENU can be customised to make additional settings or signals available to the operator.
The contents of the main display can be set to suit any condition, from a comprehensive display show-
ing all operating parameters to a simple display showing the basic signals.
Computer Connectivity
ModWeigh instruments can be connected to a computer withan RS232 connection. Data can be sent to
the PC at a preset rate. The data sent can be set up using macros.
There is also a command line interface which allows any of the settings and data to be read or written.
