Description
The CAMAC C200 module interfaces subsystem beam permit/ abort request conditions to the beam abort hardware loop and to the control system. The module was designed to meet the specific needs of the Tevatron accelerator, but has since been utilized in the Booster, Main Injector, Antiproton Source, and the Switchyard. Eight beam permit inputs are accommodated by a separate input panel. These inputs are opto-isolated, latched upon fall, and failsafe by design. Approximately, 20 ma @ 2V must be sourced externally to the module for a beam permit condition to exist. Eight current source, which are programmable from the module, are available at the input panel for connection to unused beam permit inputs. Two levels of input mask are provided at the module level. The first level is a full mask by which any or all inputs are disabled. This feature is available only if IC5 (74ALS574) is installed on the module. The second level of mask disables inputs during normal beam on time. This option for a so-called "type 1" input is set by an on-board DIP switch. The state of this switch can be read by the control system. The module receives Tevatron clock (TCLK) and the status of the upstream input. The module sources a local permit, high level permit, BP/AIP for connection to local TSCCs, and buffered TCLK. The occasion of any beam permit or the upstream permit going false is stored in an on-board FIFO register with an appropriate identifier and with a 16 bit timestamp having a resolution of 1 msec.
CAMAC Functions
All codes return Q and X immediately except F(4)A(0) for which
Q is conditional based on whether or not any values are in the
FIFO.
A) Read Functions
F0A0 - reads permitted state of each input and the
state of the type (0/1) DIP switch

F6A0 - return module ID number (200)
F9A0 - reset the module
(logical OR with Z.S2 and power up clear)
(clears input latches, FIFO, sequence circuits,
enables all inputs, all current sources on)
F9A15 - reset abort concentrator
(same as clock event $48)
(clears input latch and FIFO)
F18A0 - loads input mask and current source registers
