get(channel_list: str) → List[int][source]
# SCPI: READ:RELay:OPERations
value: List[int] = driver.read.relay.operations.get(channel_list = r1)

Queries the internal switching counter, which acquires the total number of operation cycles of each relay (and even of I/O channels) . The number of cycles is stored durable in the flash EEPROM of the module that the relay is part of. Storing occurs after every hour of R&S OSP operation, but only if the number has changed. Besides this time-controlled storing, also the query command triggers storing the counter’s value. To make sure not to lose any operation cycle counts, we recommend sending the command method RsOsp.Read.Relay.Operations.get_ before terminating a remote control session. If the module that you specify does not have a switching counter, the query always returns the value ‘0’ as the result.

INTRO_CMD_HELP: For example, the following solid-state relay (SSR) modules and digital I/O modules have no switching counter:

  • R&S OSP-B103

  • R&S OSP-B107

  • R&S OSP-B127

  • R&S OSP-B128

  • R&S OSP-B142

In the R&S OSP-B104 and R&S OSP-B114, only the electromechanical relay has a switching counter.

param channel_list

Specifies the relays and I/O channels to be read. For the channel list syntax, refer to method RsOsp.Route.Close.set.

return

switch_counts: The query returns a comma-separated string with a number for each relay or channel in the list, in the same order as the channel list is specified.

get_multiple_channels(channels: List[str]) → List[int][source]

READ:RELay:OPERations

Same as get_single_channel(), but for multiple channels.

param channels

Example value (without quotes): [‘F01M03(0002)’, ‘F01M04(0003)’]

get_single_channel(channel: str) → List[int][source]

READ:RELay:OPERations

Same as get(), but you do not need to enter round brackets or the ‘@’ character.

param channel

example value (without quotes): ‘F01M03’
