IM_busy | This bit is set when the IM processes a command. Normally, "IM_busy“ is inverted to "ready“. | |||||
| IM_busy is indicated by the IM by means of the cyclical word (refer to chapter "Cyclical Control | |||||
| Word between Master and MOBY IM“ under "IM_busy“). If processing takes place with the | |||||
| automatic command start repeat_command, this bit indicates the processing of a new MDS with | |||||
| the command that is to be executed. |
|
| |||
command_rep_active | The IM is just executing a command repetition. The bit is set as a response to the control variable | |||||
| repeat_command. After init_run, FB45 first resets the command_rep_active; it is set again | |||||
| delayed since FB45 first transmits the MOBY commands to the IM. | |||||
number_MDS | MOBY U/D or RF300: |
|
| |||
| The number of MDSs is indicated that are presently located in the transmission window. | |||||
| If more than 15 MDSs are in the field, the display number_MDS stops at 0F hex. | |||||
error_MOBY | The IM signaled this error. As a rule, this error is indicated also on the ERR LED on the IM | |||||
| channel display (refer to chapter "Error Indications and Error Search“). | |||||
error_FB | Error indication from FB45 (refer to chapter "Error Indications and Error Search“). | |||||
error_BUS | The transmission path between FB45 and the IM signals an error. As a rule, this is a PROFIBUS | |||||
| error (refer to chapter "Error Indications and Error Search“). This error is indicated by the system | |||||
| functions SFC 58/59. |
|
|
|
