♦ Bits 0 to 15:
Parameter value for 16-bit parameter or low component
for 32-bit parameter
♦ Bits 16 to 31: Value = 0 for 1-bit parameter or high component for 32-
bit parameter
♦ A task or a reply can only relate to one parameter value.
♦ The master must repeat a task until it receives the appropriate reply.
♦ The master identifies the reply to a task which has been set:
• By evaluating the reply ID
• By evaluating the parameter number, PNU
• If necessary, by evaluating the parameter index, IND
• If necessary, by evaluating the parameter value, PWE.
♦ The task must be sent complete in one telegram; telegrams with split
tasks are not permissible. The same applies to the reply.
♦ With regard to reply telegrams which contain parameter values (actual
values), the slave (CBP) always replies with the latest current values
if the telegram is repeated.
♦ If the PKW interface requires no information during cyclical operation
(only PZD data are important), the "No task" task must be sent.
When you change the initialization function of software version V1.3x to
V1.40 and higher, or VC firmware from 3.22 to 3.23 and higher, the
behavior of the converter also changes (reverting to the behavior of
software versions V1.2x and lower again) as follows:
If the electronics supply is switched off on a converter that is in state
"READY" and is connected to an automation system via a field bus
(PROFIBUS, CAN, DEVICE-NET, or CC-Link), this causes a fault
message for this converter in the automation system.
If the automation system nevertheless sends a control word STW1 with
valid authorization (bit 10 = 1) and a pending ON command (bit 0 = 1) to
this converter, this can cause the converter to switch on and go straight
into "OPERATION" state when the electronics supply is connected at the
converter.
