Specify the total number of each block within the following range.
■Block of word device, Block of bit device
Specify the device to be written by handling consecutive devices as one block.
Specify the block with the number of points equivalent to the specified "Number of word device blocks" and
"Number of bit device blocks", respectively. When '0' is specified, this specification is not required.
Specify the following items for each block.
• Device: Specify the head device of the consecutive devices. (Page 67 Devices)
• Number of device points: Specify the number of device points to be written. (Page 72 Number of device points)
• Write data: Specify the data to be written for the number of device points in hexadecimal. (Page 74 Read data, write
data)
Specify the number of device points within the following range.
Word device is 1-word per one point, and bit device is 16-bit for one point.
Use a bit device block when the contact and coil for the following devices are specified.
•Timer
• Retentive timer
• Counter
The following devices cannot be specified.
• Long timer (contact: LTS, coil: LTC, current value: LTN)
• Long retentive timer (contact: LSTS, coil: LSTC, current value: LSTN)
• Long counter (contact: LCS, coil: LCC, current value: LCN)
• Long index register (LZ)
