Value
OFF No error
ON There is an error in the output area mapping. The mapping contains an
incorrect value for either:
• the start address in the output buffer in the Master,
• the start address of the output area(s) in the PLC,
• or the size of the output area(s), or the specified size exceed the
boundaries of available buffer, DM, LR, CIO or HR areas.
OFF No error
ON There is an error in the input area mapping. The DM settings contain
an incorrect value for either:
• the start address in the input buffer in the Master,
• the start address of the input area(s) in the PLC,
• or the size of the input area(s), or the specified size exceed the
boundaries of available buffer, DM, LR, CIO or HR areas.
OFF The output mailbox was able to receive and process the previously
issued control command message.
ON The issued control command could not be processed because the out-
put mailbox was full (see section 5-2) or the RUN-bit was not set or the
bus communication was inhibited.
OFF The output mailbox is able to receive (and process) a message. This
message can be a control command issued via CIO n or any PROFI-
BUS command by using the IOWR instruction.
ON The output mailbox is full and cannot receive new messages.
OFF The input mailbox does not contain a response message to a com-
mand message issued with IOWR.
ON The input mailbox contains a response message to a command mes-
sage issued with IOWR.
00 Offline: Communication with all DP participants is stopped.
01 Stop: Only communication with DP-Master (class 2) is possible.
10 Clear: The master tries to set parameters, check configuration and per-
form data exchange with its associated DP-slaves; the slaves' inputs
are transferred to the input buffer, their outputs are cleared.
11 Operate: The master exchanges data with the assigned DP-slaves.
-- Error numbers CIO n+3 contains error messages related to either a
specific slave device or the Unit itself. For detailed error code, refer to
the C200HW-PRM21 PROFIBUS DP Master Unit Operation Manual
(W349-E2-@).
00~7D The Error number is related to a specific slave device, as indicated by
the station number.
FF The Error number is related to the Unit itself.
001~12 When CIO n+2.13 is set (Reply in output mailbox), this CIO word con-
8
tains the length of the message that can be retrieved with an IORD
0~F
instruction. Combined with the Unit number, this constitutes the correct
source information for the IORD instruction. Refer to the C200HW-
PRM21 PROFIBUS DP Master Unit Operation Manual (W349-E2-@).
