4–6 Communicating on the Ethernet Network
Publication 1747-10.4
When the processor detects an error during the transfer of message
data, the processor sets the .ER bit and enters an error code that you
can monitor from your programming software.
Error Code Description of Error Condition
02H
Target node is busy. The MSG instruction automatically reloads. If other messages are waiting, the message is
placed at the bottom of the stack.
03H Target node cannot respond because message is too large.
04H
Target node cannot respond because it does not understand the command parameters OR the control block was
inadvertently modified.
05H Local processor is offline (possible duplicate node situation).
06H Target node cannot respond because requested function is not available.
07H Target node does not respond.
08H Target node cannot respond.
09H Local modem connection was lost.
0AH Buffer unavailable to receive SRD reply.
OBH Target node does not accept this type of MSG instruction.
0CH Received a master link reset (one possible source is from the DF1 master).
10H Target node cannot respond because of incorrect command parameters or unsupported command.
11H Local file has constant file protection.
12H Local channel configuration protocol error exists.
13H Local MSG configuration error in the Remote MSG parameters.
15H Local channel configuration parameter error exists.
16H Target or Local Bridge address is higher than the maximum node address.
17H Local service is not supported.
18H Broadcast (Node Address 255) is not supported.
19H Improperly formatted Logical ASCII Address string. String not properly terminated with a NULL character, or the string
length does not match the value in the length parameter.
20H PCCC Description: Host has a problem and will not communicate.
30H PCCC Description: Remote station host is not there, disconnected, or shutdown.
37H Message timed out in local processor.
38H Message disabled pending link response.
40H PCCC Description: Host could not complete function due to hardware fault.
50H Target node is out of memory.
60H Target node cannot respond because file is protected.
70H PCCC Description: Processor is in Program Mode.
80H PCCC Description: Compatibility mode file missing or communication zone problem.
90H PCCC Description: Remote station cannot buffer command.
B0H PCCC Description: Remote station problem due to download.
C0H PCCC Description: Cannot execute command due to active IPBs.
D0H No IP address configured for the network, –or–
Bad command – unsolicited message error, –or–
Bad address – unsolicited message error, –or–
No privilege – unsolicited message error
D1H Maximum connections used – no connections available.
D2H Invalid internet address or host name.
D3H No such host / cannot communicate with the name server.
