      abstract     = {Control systems of neutron instruments are responsible for
                      the movement of a variety of mechanical axes. In the TANGO
                      based control systems developed by Forschungszentrum Jülich
                      for neutron instruments, Siemens S7-300 PLCs with single
                      axis stepper motor controllers from Siemens or Phytron have
                      been used for this purpose in the past. Synchronous
                      coordinated movement of several axes has been implemented
                      with dedicated 4-axes NC modules (FM357) for the S7-300. In
                      future, the recent S7-1500 PLC family shall be used for
                      motion tasks. With the S7-1500, stepper motor control is
                      possible with low-cost fast digital outputs, so called PTOs
                      (pulse trade outputs). The integrated motion functions of
                      the S7-1500 directly support synchronous movement. The
                      function block interface defined by PLCopen serves as a
                      homogeneous programming interface which is independent of a
                      specific motion controller. For the single crystal
                      diffractometer HEiDi at the research reactor FRM-II a
                      replacement for a S7-300 with FM357 has been implemented
                      based on a S7-1500 PLCs and a PTO module.},
