instruction, and retry the operation.
• Set 1 to 2 for the target channel number in the control data when
executing the SEND instruction.
• Correct the number of the channel used by own station in the
control data, and retry the operation.
• The value set for the control block of the dedicated instruction is
out of range. Correct the value and retry the operation.
