Plan to Use Your Adapter 3-3
Connection Limit
Exceeded Error
The connection limit exceeded error (0x0113) on the Module
Properties dialog is shown below.
When the 1734-ACNR connection limit is exceeded, you will get an
0x0113 error. The 1734-ACNR connection limit is 600 bytes.
This condition can exist when the modules connected to the
1734-ACNR adapter overflow the adapter’s transmit buffer. This
condition is rare with most POINT I/O modules.
A combination of 25 analog I/O and 38 digital I/O with direct and
rack connections, respectively, should not result in this error.
However, the 1734-232ASC Serial Interface ASCII module can transmit
up to 134 bytes.
Five of these modules configured to a maximum data size will
overflow the 1734-ACNR transmit buffer.
Proper planning should prevent this error from occurring. Notice that
the 1734-232ASC module default configuration is 80 bytes.
