Up to 32 PC830s can be connected in parallel to a multidrop master. The PC830s must each have a unique address, set in software. Once the address is set, the Axis Selection function in 830 Tools must be used to select the designated axis address. Then, either the RS-232 or the RS-485 link can be used to communicate with the selected axis. For example, the RS-232 link can be used to completely setup and test an individual axis before connecting it into the multi-axis configuration. RS-485/RS-422 connections to J1 are shown below. A multidrop interconnection diagram, showing multiple axes connected to a single host is also shown.
RS-232/RS-485 converter installation
It is often convenient to use an RS-232 to RS-485/RS-422 converter so that an RS-232 port, available on all PCs, can be used to connect to multiple axes. The figure below shows a typical installation, using theB&B Model 422 RS-232 to RS-422 adapter. RS-232 to RS-485/RS-422 adapters are available from many sources. Note: An adapter can be powered from the serial port +5 Vdc output on J1-4 as long as the load current on J1-4, J2-14, and J3-10 total less than 250 mA.
Command I/O
Analog CMD (+), (-) Inputs J2-1, 2 These inputs accept the analog command from the user. This is a differential input to an A/D. It has a maximum single ended input range with respect to I/O RTN on either input of ± 21V and an input impedance of 50kΩ. The full scale differential command input range is ± 13.5 V. The offset and single pole low pass bandwidth of this signal is adjustable via a software setup parameter. When used as a motion command the gain from this input is also adjustable via a software setup parameter.
