63. status data can be written by communication Restrictions on read Any parameters which cannot be called by key operation on the instrument can be all called by communication If an address out of the range non designated address is accessed the status code 23 is returned e Restrictions on write Any parameters which cannot be input by key operation on the instrument can be written by communication The restrictions on write the high and low limits etc are the same as in the usual input by a console Even a parameter which can be input by key operation may not be able to be set by communication under an inappropriate condition In case more than one data including error data are to be written in once message For example assume that the proportional band integral time and derivative time are written like WS 5001W 300 8000 20 Since I then exceeds the effective range the response 48 error response is returned At this time beware of the following points DData is written until a set disable data appears 2 No data is written at a word address where a set disable data exists but the next data is processed In the case of this example therefore 300 and 20 are written normally but 8000 is not written and the value before the message is received remains 5 3 5 Communication data table e Status write The status write command makes the LSB side of bit information effective For example wh
