^1 Compliant with JIS B 3502 and IEC 61131-2, No. of scans: 10 times in each of the X, Y, and Z directions (for 100 min.) ^2 The maximum current consumption is 3.4 A when using KV-X550, KV-X530, or KV-X520. ^3 Specify 0 or a positive integer for the subscript. A conversion or calculation error will occur if any other number is specified. ^4 Only structured text can use calculation expressions as subscripts. Calculation expressions cannot be used as subscripts in ladder programs. ^5 When writing stAAA.member, the number of nested rows will be 1. When writing stAAA.stBBB.member, the number of nested rows will be 2. ^6 It may not be possible to use other Ethernet functions at the same time as the OPC UA function. ^7 Only one of the ports can use the OPC UA Server function at a time. ^8 Number of monitor items is the number of elements set as the target of cyclic communication with OPC UA client. The number of monitor items is the result of counting the actual number of variables irrespective of the size of the variable. Each registered structure/array type variable is counted as one monitor item. The maximum number of published network variables can be monitored by defining the relevant data collectively as a structure type variable. ^9 Sampling cycle is set on the OPC UA client. The OPC UA server operates at an integer multiple of 10 ms independent of the sampling cycle set in the client. ^10 Includes the number of structure members and the number of array elements. ^11 Method calls are only available when the companion specification is applied. ^12 Reading and writing is possible only for the Value attribute. ^13 The maximum current consumption is 3.2 A when using KV-X310. ^14 The KV-X310 cannot be used as an OPC UA client.
