An electrohydraulic system includes a plurality of electrohydraulic devices individually controlled by microprocessor-based control electronics. The device controllers are connected in common by a bidirectional serial data bus to a master controller for coordinating operation of the various devices. Internal programming within the master controller establishes a repetitive time-sequence of windows for communications with the various device controllers for downloading control signals and parameters, and for uploading data indicative of system status and operation. The various device controllers include internal programming for operating the associated hydraulic devices as a function of control signals and parameters received from the master controller. Pseudo-devices are also connected to the bus for time-division multiplexed communication with the master controller and for performing overall system coordination and analysis.

A machine tool table is disclosed having a lock accessible at the front of the table for applying pressure through a connection to a rear board so that a fence and at least one table spacer are held in position between the rear board and the front table. The lock may be adjusted at the front table to release the pressure so that the position of the fence may be changed.
