SETTING SYSTEM FOR CIRCUIT SCAN MODE

PURPOSE:To decrease the number of program production processes and to improve the storing flexibility of collected lines, by giving the arithmetic processing to the circuit discrimination information set to a circuit adaptor and collating this information with the conditions accordant with a system to set automatically a circuit scan mode. CONSTITUTION:The circuit discrimination information accordant with each circuit is set previously to each register of circuit adaptors 4-1-4-3 respectively. Both a boot strap program for loading and a program for initialization are loaded to a buffer memory 2 and executed in order to read said discrimination information and to set an optimum can mode. Thus the coded circuit speed and transmission control procedure which are set for each circuit to be controlled are read out of a register for circuit discrimination information by a microprocessor 1 based on a program loaded to the memory 2. The processor 1 checks whether or not the read-out circuit speed and control procedure comply with the circuit storing conditions. Then an optimum scan mode is set and stored to a control table of the memory 2.
