If slave devices have a slow start-up, the master can delay for a short time before performing
slave station configuration; this time delay can be set via D1092.
Special D
D1092
With regard to slave device initialization, a delay time can be set to judge whether failure has
occurred. If the communications speed is relatively slow, the delay time can be adjusted to judge
whether initialization has been completed, which will ensure that there is time to perform slave
device initialization.
Special D
D1099
After communication is successful, the system must detect whether there is a break in
communications with the slave station. D1093 is used to set detection time, and D1094 sets the
number of consecutive errors that will trigger a break error.

The packet type transmitted by PDO is set before establishing normal communications and
generally does not require adjustment.

The third block is the slave station mapping and control area.
CANopen provides a PDO method to perform mapping of the master and slave station memory,
and enables the master to directly access read/write data in a certain memory area. The master
will automatically perform data exchange with the corresponding slave device, and the
read/write values can be seen directly from the special D area after real-time exchange (M1034
= 1 time) has been established. The CFP2000 currently supports real-time mapping of four
PDOs, and there are two types of PDO RXPDO (reads slave device information) and TXPDO
(writes to slave device). In addition, in order to facilitate control, the CFP2000 cannot perform
mapping of commonly used registers; the following is an overview of the current PDO mapping
situation:
