Additional indications

The displays indicate to the user the progress of a command. Error analyses are easy to perform.

Variable Description

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.

Display of the firmware version of the MOBY IM. The value entered here is updated after every IM

power-up . It is ASCII encoded.
